A plumber charges his customers $25.70 per hour, h, plus a $54.50 service fee. On Tuesday, he earns $118.75 for fixing Mrs. Goodwill's sink. How long does it take the plumber to fix Mrs. Goodwill's sink

2.5 hours

Step-by-step explanation:

Given that :

Charge per hour = 25.70

Service fee = $54.50

If total earning = 118.75 ; how many hours did it take to fix the sink?

Let number of hours = x

Total earning = service fee + (charge per hour * number of hours)

118.75 = $54.50 + (25.70x)

118.75 - 54.50 = 25.70x

64.25 = 25.70x

x = 64.25 / 25.70

x = 2.5

Hence, it took 2.5 hours to fix the sink
