The question:
"There have been two proposals for ticket sales. The first proposes a base fee of $5 for entry into the park and $0.50 per ride. The second plan has no base fee, but charges $0.75 per ride. After How many rides would the cost[s] be equal?"
Step-by-step explanation:
Assume that the two costs become equal after rides.
- The first plan will cost dollars.
- The second plan will cost dollars.
The two costs are assumed to be equal. That is:
.
Subtract from both sides of this equation:
.
.
In other words, the two costs become equal after 20 rides.
