Claire is going to an amusement park. The price of admission into the park is $30, and once she is inside the park, she will have to pay $4 for every ride she rides on. How much money would Claire have to pay in total if she goes on 9 rides? How much would she have to pay if she goes on r rides?

1. $66

2. 30 + 4r

Step-by-step explanation:

Let

Price of admission into the park=$30

Price of every ride in the park=$4

Number of rides =x

Total cost of going to the park= 30+4x

1. How much money would Claire have to pay in total if she goes on 9 rides

Total cost of going to the park= 30+4x

When x=9

=30+4x

= 30 + 4(9)

=30 + 36

=$66

2. How much would she have to pay if she goes on r rides?

When x=r

Total cost of going to the park= 30+4x

= 30 + 4(r)

=30 + 4r
