The school store received a shipment of notebooks and pens. There are 10 cartons of notebooks and 25 boxes of pens. Each carton of notebooks costs $72 and contains 48 notebooks. Each box of pens costs $12.60 and contains 36 pens. The school wants to make a 10% profit.
question What is the cost of one notebook? What amount must be added on to the notebook's cost to account for a 10% markup? What will be the retail price (price the school is charging) for the notebook?
Answer:
cost of one notebook: 72/48 = $1.50
10% mark up = $1.50 x 0.10 = 0.15 cents
retail price = $1.65

Daria pays x dollars for a pair of shoes. The tax on shoes is 5%. The expression
representing her total cost is x +0.05x.
Which expression is equivalent and why?
1.5x because adding 5% to the cost of the shoes is the same as
multiplying the cost by 1.5.
1.05x because adding 5% to the cost of the shoes is the same as
multiplying the cost by 1.05.
0 x10.05) because the cost of the shoes can be factored out.
1.05x because adding $5 to the cost of the shoes is the same as
multiplying the cost by 1.05.
Answer:
B. 1.05x because adding 5% to the cost of the shoes is the same as multiplying the cost by 1.05.
Step-by-step explanation:
Cost of a pair of shoe = $x
Tax on shoes = 5% of x
= 0.05 x
The total cost of shoe = cost price + tax
= $x + 0.05x
= $1.05x
This means that she would pay 1.05 multiplied by the cost of the shoes.
Example, assume that the cost of the pairs of shoe is $20, then;
Total cost = 1.05 x 20
= $21.00
Thus, it can be inferred that adding 5% to the cost of the shoes is the same as multiplying the cost by 1.05.
Answer:
B. 1.05x because adding 5% to the cost of the shoes is the same as multiplying the cost by 1.05.

What is the correct description for the system of linear equations?
y=−2x+5
2x+y=5
a. consistent independent
b. consistent dependent
c. inconsistent
Answer:
Step-by-step explanation:
A linear equation is not always in the form y = 4.5 − 0.5x,
It can also be like y = 0.2(7 − x)
Or like y + 0.2x = 4.5
Or like y + 0.2x − 4.5 = 0 and more.

Ethan planted a tree that was 1.85 m tall seven years later the tree is 5.30 m tall which equation can be used to finance the number of meters the tree has grown
Answer:
The answer is below
Step-by-step explanation:
Let h represent the height of the tree in meters and t represent the number of years after planting.
Initially a tree of height 1.85 m was planted, i.e. at t = 0, h = 1.85. It can be represented in form of (h, t) as (1.85, 0).
After seven years the height of the tree was 5.30 m, it can be represented as (5.30, 7). Hence the equation can be gotten using:
[tex]t - t_1=\frac{t_2-t_1}{h_2-h_1} (h-h_1)\\\\t-0=\frac{7-0}{5.30-1.85}(h-1.85)\\\\t= 2.03(h-1.85)\\\\t=2.03h-3.75[/tex]

Trevion is training for a marathon. In February, he ran XLVII miles for his training. In January, he was only able to run XXIV miles. How many more did he run in February than in January?
Answer:he ran 23 miles / XXIII miles more in February than March
Step-by-step explanation:
February = He ran XLVII --- converting to numbers becomes
XL= 40
VII= 7
XLVII= 47
In march he ran XXIV--- converting to numbers becomes
XX= 20
IV= 4
XXIV= 24
Step 2
To find how many more he ran in February than March
Miles ran in February - Miles ran in March
47- 24=23.
Therefore he ran 23 miles / XXIII miles more in February than March

Answer:
no its not
Step-by-step explanation:
x-11 is only supposed to have one y.
if its a funtion then x should only have one line comming out of it. if its not a finction then x has two lines coming out of it.
Answer: no because the x axis dont equal or match up with the y axis and because theres not a certain amount of numbers for it to equal to or match to.
Step-by-step explanation:
A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2. please give me brainliest

Flying against the wind, an airplane travels 5040 kilometers in 6 hours. Flying with the wind, the same plane travels 6000 kilometers in 5 hours. What is the rate of the plane in still air and what is the rate of the wind?
Answer:
The rate of plane in still air is 1020 kilometers per hour and rate of wind is 180 kilometers per hour.
Step-by-step explanation:
Given that:
An airplane travels 5040 kilometers in 6 hours against the wind
An airplane travels 6000 kilometers in 5 hours with the wind
Let,
x be the speed of plane in still air
y be the rate of wind
Combined speed against the wind = x - y
Combined speed with the wind = x+y
Speed = [tex]\frac{Distance}{Time}[/tex]
x-y= [tex]\frac{5040}{6} = 840[/tex]
x - y = 840 Eqn 1
x + y = [tex]\frac{6000}{5} = 1200[/tex] Eqn 2
Adding Eqn 1 and 2
x+y+x-y=1200+840
2x=2040
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{2040}{x}\\x=1020[/tex]
Putting x=1020 in Eqn 2
1020+y=1200
y=1200-1020
y=180
Hence,
The rate of plane in still air is 1020 kilometers per hour and rate of wind is 180 kilometers per hour.
