Question

Evan is going to the county fair this weekend. The admission to the fair is $5 and the cost per ride is $.50. Write and solve a linear equation to find out how many rides he can go on.

Answer 1

Evan can go on 30 rides (based on the assumption that Evan's parent gave him $20)

Explanation:

Given that:

The admission to the fair = $5

The cost per ride = $0.50

Let assume that the number of ride Evan can go = x

So if The cost per ride = $0.50

x ride = $0.50x

We are not told that he is given money by anybody, but let assume his parent gave him $20,

Then, if Evan pays $5 for admission into the fair. Then he will have $(20-5) = $15 left

The relation expressing how many rides Evan can go is:

0.5x = 15

Since the cost per ride = $0.5

x rides cost $15/0.5

x = 15/0.5

x = 30

Hence, Evan can go on 30 rides
