Final answer:
The dependent variable is the total fee and the independent variable is the number of hours the equipment is rented. The equation to express the total fee in terms of the number of hours is Total fee = Up-front fee + Hourly fee x Number of hours.
Step-by-step explanation:
The dependent variable is the total fee and the independent variable is the number of hours the equipment is rented. The total fee depends on the number of hours.
To find the equation that expresses the total fee in terms of the number of hours, we can use the formula:
Total fee = Up-front fee + Hourly fee x Number of hours
In this case, the up-front fee is $25 and the hourly fee is $12.50. So the equation would be:
Total fee = $25 + $12.50 x Number of hours
