Answer 1

Given:

In the first option, Charlie can pay $39 for unlimited rides,

In the second option, Charlie can pay $15 for admission plus $1 per ride.

Required:

We need to find the number of rides that the two options wind up costing him the same amount.

Step-by-step explanation:

Let C be the cost of the ride.

Let r be the number of the ride.

Consider the first option.

`C=39`

Consider the second option.

`C=15+r(1)`

Substitute C=39 in this equaiton.

`39=15+r(1)`

Substract 15 from both sides of the equation.

`39-15=15+r(1)-15`

`24=r`
`r=24\text{ rides.}`

The number of rides that the two options wind up costing him the same amount is 24 rides.

The cost of the ride is C =39.

Final answer:

The number of rides =24.

The cost of the rides =39.
