Question

A cable television repairman charges $35 to go to a customer’s home. He charges an additional $20 per hour for the repair. Petra paid the repairman a total of $85 to come to her home and make a repair. How many hours did it take for the repairs?

Answer 1

Answer: It took 2 and a half hours for the repairs

Step-by-step explanation:

subtract 35 dollars from the total payed of 85 dollars you're left with 50 dollars we know the repairman charges and extra 20 dollars for every hour he's doing the repairs divide the 50 dollars more she had to pay and divide it by the 20 dollars he charges per every hour he's making repairs and you'll get 2.5 hours

Answer 2

The number of hours used for the repair is 2 1/2 hours.

Let the number of hours used for the repair be represented by h

Based on the information given, the equation to solve the question will be:

35 + (20 × h) = 85

35 + 20h = 85

Collect like terms

20h = 85 - 35

20h = 50

Divide both side by 20

20h/20 = 50/20

h = 2.5 hours

In conclusion, it took 2 1/2 hours for the repair.
