To find the total cost of a 5-hour bike tour, you can break it down into two parts: the fixed equipment cost and the variable cost based on the number of hours.
1. **Fixed Equipment Cost**: This is the initial cost of renting the equipment, which is $50.
2. **Variable Cost per Hour**: The cost for each hour of the tour is $7.50. Since the tour lasts for 5 hours, you would multiply the cost per hour by the number of hours:
\[
\text{Variable Cost} = \text{Cost per hour} \times \text{Number of hours} = 7.50 \times 5
\]
Performing the calculation:
\[
7.50 \times 5 = 37.50
\]
3. **Total Cost**: Finally, you add the fixed equipment cost to the variable cost calculated above:
\[
\text{Total Cost} = \text{Fixed Equipment Cost} + \text{Variable Cost} = 50 + 37.50
\]
Performing this addition:
\[
50 + 37.50 = 87.50
\]
So, the total cost of a 5-hour bike tour would be **$87.50**.

\]
So, the total cost of a 5-hour bike tour would be **$87.50**.
