Question

An electrician charges a service charge of $35 plus $22 per hour. If the final bill for the electrical repair is $160 which equation represents cost for H,number of hours?

Answer 1

x = number of hours

service cost = $35

he charged $160 for the cost of service and hours spent

knowing that he charges $22 per hour

on write the equation

22x+35=160

22x=160-35

22x=125

x=5.68...h = 5h40min

Explanation:

Answer 2

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
