Let's denote the hourly fee as h.
Given:
Initial fee = $43
Total amount paid after 7 hours = $64
The total amount paid can be represented by the equation:
Total amount = Initial fee + (Hourly fee * Number of hours)
$64 = $43 + h * 7
Solving for h, the hourly fee:
$64 = $43 + 7h
$64 - $43 = 7h
$21 = 7h
h = $21 / 7
h = $3
Therefore, the hourly fee for the rototiller is $3 per hour.
The equation that models this problem is:
Total amount = $43 + $3 * Number of hours
or
Total amount = $43 + 3h
