Every 8th customer gets a free appetizer.
Every 12th customer gets a free beverage.
Every 15th customer gets a free fish of yogurt.
To find:
The first customer to receive all the three items.
Solution:
Here, we need to find nothing but the Least Common Multiple of the given three numbers 8, 12 and 15 to find the first person who will get all three free items.
Let us use factors of each number:
[tex]8 = 2\times 2\times 2\\12 = 2\times 2\times 3\\15 = 3\times 5[/tex]
The LCM will be:
[tex]2\times 2\times 2 \times 3 \times 5 = \bold{120}[/tex]
Therefore, the answer is:

Marco went to the cafeteria to buy chicken sandwiches, C, worth $2.00, and hamburgers, h, worth $2.50.
He bought a total of 9 items and spent a total of $20.50. How many hamburgers and chicken sandwiches
did Marco buy?
HELP
Answers
Answer:
5 Hamburgers = $12.50 4 Chicken sandwiches $8.00( $12.50 + $8.00 = $20.50
Step-by-step explanation:
Answer:
Marco bought 5 hamburgers and 4 chicken sandwiches.
Step-by-step explanation:
Set up a system of equations:
2c + 2.5h = 20.5
c + h = 9
Solve by elimination by multiplying the bottom equation by -2:
2c + 2.5h = 20.5
-2c - 2h = -18
Add the equations together and solve for h:
0.5h = 2.5
h = 5
So, he bought 5 hamburgers. Plug in 5 as h into the second equation to solve for c:
c + h = 9
c + 5 = 9
c = 4
So, Marco bought 5 hamburgers and 4 chicken sandwiches.

If 4(r + 2) – 13 = 11, what is the value of r?
Answers
Answer:
r = 4
Step by step explanation :
Step 1 : Add 13 to both sides.
4(r + 2) - 13 + 13 = 11 + 13
4(r + 2) = 24
Step 2 : Divide by 4 on both sides.
[tex]\frac{4(r+2)}{4} = \frac{24}{4}[/tex]
r + 2 = 6
Step 3 : Subtract 2 from both sides.
r = 4
The value of r is 4 in the given expression and this can be determined by using the arithmetic operation.
Given :
Expression - 4(r + 2) – 13 = 11
The following steps can be used to evaluate the given expression:
Step 1 - Write the expression.
4(r + 2) – 13 = 11
Step 2 - Add 13 on both sides in the above equation.
4(r + 2) – 13 + 13 = 11 + 13
4(r + 2) = 24
Step 3 - Multiply 4 by (r + 2) in the above expression.
4r + 8 = 24
Step 4 - Subtract 8 on both sides in the above expression.
4r + 8 - 8 = 24 - 8
4r = 16
Step 5 - Divide 4 on both sides in the above equation.
r = 4
The value of r is 4.

Answers
Answer:
This description translated into an inequality is
x + 15 > 124
x > 109
X is greater than 109
This means that the smallest integer that satisfies this inequality is 110 because X cannot be 109 or less; it is greater than 109.
We did not say 109.1 or 109.2 or 109.99 because it is asking for an integer, which cannot be a decimal.
