Question

The carnival charges $5 admission and $0.50 for each ride. Alex's dad gave him $15 to spend. How many rides can he go on at most? Write and solve an inequality to answer the question.

Answer 1

Let us suppose number of rides is x.One ride costs $0.50.

Cost of x rides is 0.50x. The carnival charges is $5. Alex has $15 to spend .

Number of rides at most Alex can have can be given by the inequality:

0.50x+5≤ 15

To solve for x we subtract 5 both sides

0.50x≤ 15-5

0.50x≤ 10

Dividing both sides by 0.50 we have :

x≤ 20

Number of rides at most Alex can have is 20.

Answer 2

He can ride on 20 rides. 15-5=10 then 10/.50=20. Hope that helps
