Question

It costs $20.50 to enter an amusement park and $0.25 to ride a ride. You have $21.50. Write an equation that represents the number r of rides you can ride.

An equation is
________ =21.50.

Answer 1

4

Explanation:

`0.25\:r + 20.50 = 21.50\\</p><p>0.25\:r = 21.50 - 20.50\\</p><p>0.25\:r = 1\\</p><p>r = (1)/(0.25)\\</p><p>r = (100)/(25)\\</p><p>r = 4\\`

Answer 2

Answer: 0.25r + 20.50= 21.50; You'd only be able to go on four rides.

Let r represent how many rides you can go on

21.50-20.50 ( Money you have now - cost to enter), this leaves you with $1 left.

0.25r = $1

0.25(4)= $1

Therefore r =4. And you would only be able to go on four rides.
