Question

Eric and Mark were at a ball game and visited the concession stand. They each got a hamburger, and Mark got a lemonade and some cotton candy. Eric had a coupon for $2 off the cost. Mark paid the rest, which came to $14.50. Cotton candy costs $5, and a hamburger costs $4. How much is lemonade?
A. $7.50
B. $1.50
C. $4.00
D. $3.50

Answer 1

Write an out an equation using the information given. So:

8 + 5 + x - 2 = 14.5 
13 + x - 2 = 14.5 
11 + x = 14.5 
x = 3.50

This means that the answer is D.

Hope this helped  :)

Answer 2

The answer is $7.50
14.50+$2 off=16.50(total price)
16.50-9.0=$7.50
