Answer:

He earned approximately $ 9.87 per hour.

Step-by-step explanation:

The given selling price of the lawn mower = $ 155.00

Since, His spending for the lawn = The cost price of the lawn + Spending in parts repair + Spending in polishing and paint

= $35.00 +$39.17 + $36.43

= $ 110.60

Thus, the profit he gain by selling = Selling price - His total spending

= 155.00 - 110.60

= $ 44.4

Since, the procedure took 4.5 hours,

His earning in 4.5 hours = $ 44.4

⇒ His earning in 1 hour = 9.86666666667 ≈ $ 9.87

Hence, he earned approximately $ 9.87 per hour.
