Answer:
22h + 35 = 160
Explanation:
Let h = number of hours.
He charges $22 per hour, so the hourly part of the total cost is 22h.
The fixed service charge is $35.
The total charge is the hourly part of the charge plus the fixed service fee.
Total charge = 22h + 35.
The total charge was $160.
Equation:
22h + 35 = 160
