Stefan’s family rented a rototiller to prepare an area in their backyard for spring planting. The rental company charged an initial fee of $43 with an additional fee per hour. If they paid $64 after renting the rototiller for 7 hours, what was the hourly fee?

If h represents the hourly fee, which equation models this problem?



What was the hourly fee for the rototiller?

Sagot :

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
