Question

Tristan is going to an amusement park. The price of admission into the park is $40, and once he is inside the park, he will have to pay $5 for every ride he rides on. How much money would Tristan have to pay in total if he goes on 9 rides? How much would he have to pay if he goes on rr rides?
Answer
Attempt 1 out of 2

Cost with 9 rides:
Cost with r rides

Answer 1

To calculate the total cost for Tristan to attend the amusement park, we need to consider both the admission price and the cost per ride.

1. **Cost with 9 rides**:
- Admission price: $40
- Cost per ride: $5
- Number of rides: 9

Total cost for 9 rides = Admission price + (Cost per ride × Number of rides)
= $40 + ($5 × 9)
= $40 + $45
= $85

2. **Cost with r rides**:
- Admission price: $40
- Cost per ride: $5
- Number of rides: r

Total cost for r rides = Admission price + (Cost per ride × Number of rides)
= $40 + ($5 × r)
= $40 + 5r

In summary:
- Cost with 9 rides: $85
- Cost with r rides: $40 + 5r
