Javier had $305 in his bank account. His bank charges a fee of $7.50 each month that a balance is below $500. If he makes no other deposits or withdrawals, how much money is in Javier’s account at the end of three months? Write an equation and solve.
Answer:
$282.5
Step-by-step explanation:
$7.50 * 3= $22.5
$22.5 is the total money that is charged from Javier's bank account.
Subtracting that from his $305, we get:
$305 - $22.5 = $282.5
Therefore, Javier has $282.5 in his bank account at the end of three months.
Hello 928747!
So Javier has $305 to begin with but his bank charges him $7.50 if he has less than $500 in his account.
305 < 500
So, since he has less than $500 he will lose $7.50
305 - 7.50 = 297.50
So after they take $7.50, he will have $297.50
but he had less than $500 for 3 months so they would take x 3 more than $7.50
7.50 x 3 = 22.50
305 - 22.50 = 282.50
After three months, Javier will have $282.50

Solve the real-world situation by using the substitution method. The number of DVDs sold at a store in a month was 935 and the number of DVDs sold decreased by 12 per month. The number of Blu-ray discs sold in the same store in the same month was 517 and the number of Blu-ray discs sold increased by 26 per month. Let d represent the number of discs sold and t represent the time in months. The system of equations lbrace d = 935 − 12t d = 517 + 26t can be used to represent this situation. If this trend continues, how many months will the number of DVDs sold equal the number of Blu-ray discs sold? How many of each is sold in that month? There will be ______ DVDs and Blu-Ray discs sold per month in ______ months.
Answer:
t = 11 months
d = 803
Step-by-step explanation:
d = 935 − 12t
d = 517 + 26t
how many months will the number of DVDs sold equal the number of Blu-ray discs sold
Equate both equations to solve for the number of months
935 − 12t = 517 + 26t
935 - 517 = 26t + 12t
418 = 38t
t = 418 / 38
t = 11 months
How many of each is sold in that month?
d = 935 − 12t
= 935 - 12(11)
= 935 - 132
= 803
d = 517 + 26t
= 517 + 26(11)
= 517 + 286
d = 803
There will be 803 DVDs and Blu-Ray discs sold per month in 803 months.

If she only worked 1 day and had $20, then the answer is
20 * 3% = 20 * .3 = $6.0
Answer:
Hi! I believe the answer is 6$
Step-by-step explanation:
If you are trying to get 30% of 20, you divide 20 by 30. You would then get .6666666 or 6. I double-checked my answer online!

Is this a function?
{(2, 4), (2,5), (2,6), (2,7)}
Answer:
No
Step-by-step explanation:
For a relation to be a function it must have a unique x-value for every y-value. This means that in a function x-values cannot repeat. In this relation, the x-value repeats multiple times, so it is not a function. It is also a vertical line, and vertical lines can never be functions since the x-value is constant and therefore repeats.
Solving equations using Zero-Product property
Please Help! and i need an explanation... i just don't understand and my teacher didn't explain
2y(-8y+7)=0
Answer:if y=0
Step-by-step explanation: view y as 0, so you have 2*0*(-8+0+7)=0
every number multiplied by 0 is 0 so 2*0 is 0 then in the brackets you will have -1. So the final line is 0*-1=0 like I said every number multiplied for 0 is 0 the equation is true for y=0
Answer:
see explanation
Step-by-step explanation:
The zero product property applies to the product of factors equal to zero
For example
a × b = 0
Since the product of the 2 numbers is zero , then one of the numbers must be zero, that is
a = 0 or b = 0
This can be applied to the product
2y(- 8y + 7) = 0
The 2 values being multiplied are 2y and (- 8y + 7)
Thus one or the other must equal zero, so solve both
2y = 0 ⇒ y = 0, or
- 8y + 7 = 0 ⇒ - 8y = - 7 ⇒ y = [tex]\frac{-7}{-8}[/tex] = [tex]\frac{7}{8}[/tex]

Please help me find an equation for this
Answer:
The equation that represents this situation is x + 3x + (x - 4) + 2(x - 4) = 72, where x is Erik's age
Step-by-step explanation:
Let us solve the question
Assume that Erik is x years old
∵ Erik is x years old
∵ Erik is [tex]\frac{1}{3}[/tex] as old as Dawn
→ That means x = [tex]\frac{1}{3}[/tex] Dawn
∴ x = [tex]\frac{1}{3}[/tex] Dawn
→ Multiply both sides by 3
∴ 3x = Dawn
∴ Dawn is 3x years old
∵ Jiro is 4 years younger than Erik
→ That means Jiro = x - 4
∴ Jiro is (x - 4) years old
∵ Alita is 2 times as old as Jiro
→ That means Alita = 2 × (x - 4)
∴ Alita = 2 × (x - 4)
∴ Alita is 2(x - 4) years old
∵ The sum of all their ages is 72
→ That means add their ages and equate the sum by 72
∴ Erike's age + Dawn's age + Jiro's age + Alita's age = 72
∴ x + 3x + (x - 4) + 2(x - 4) = 72
The equation that represents this situation is x + 3x + (x - 4) + 2(x - 4) = 72, where x is Erik's age

A person standing 154 feet from the base of a church observed the angle of elevation to the church's steeple to be 25∘. How tall is the church?
Answer:
71.764 feet
Step-by-step explanation:
See attached the rough sketch for your reference
Step one;
Given data
The angle of elevation= 25°
From the triangular diagram, we can see that the height of the church is the opposite, while the distance of the person from the church is the adjacent
Step two:
Applying SOH CAH TOA
tan∅= opp/adj
tan 25= opp/154
0.466= opp/154
cross multiply
0.466*154= opp
opp= height of church = 71.764 feet

You are the manager at an amusement park. The park's maximum capacity is 4500 people. You have also worked out that there needs to be 2800 people in the park to make a profit after all the overhead costs and employee pay. If people are entering the park at a rate of 12 people a minute and there are 850 people in the park currently, between how many minutes should the door stay open to let guests in?
Answer:
if you need the compound equality it is 2800 ≤ 850 + 12m ≤ 4500
Step-by-step explanation:
m= minutes 2800 is the minimum 4500 is the maximum 850 is from the people already in the park and 12m came from the people coming in per minute so i multiplied the 12 by m
Veronica saved up her tutoring money to buy video games. She buys 2 games for $30.00 each and a game controller for $19.59. Veronica lives in San Jose, California, where sales tax is 9.25%. Which of these gives the correct amount of sales tax AND the total (with tax included)? If necessary, round the amount of tax to the nearest 100th.
Answer: See explanation
Step-by-step explanation:
Since Veronica buys 2 games for $30.00 each and a game controller for $19.59. The total cost to be paid will be:
= (2 × $30.00) + $19.59
= $60.00 + $19.59
= $79.59
Since Veronica lives in San Jose, California, where sales tax is 9.25%, the sales tax will be:
= 9.25% × $79.59
= 0.0925 × $79.59
= $7.36
Total amount paid = $79.59 + $7.36 = $86.95
