Question

a repairman charges an inspection fee plus 20 per hour. A customer with a coupon for 30% off the inspection fee pays $95 for a 3 hour repair. How many hours are worked when a customer pays $130 without a coupon?

Answer 1

Answer:

$108.50 for the 30% off and 1h 35min without the coupon

Step-by-step explanation: 60+95=155

155x0.30=46.5

155-46.5=108.50

Answer 2

Answer:

4.2 hours

Step-by-step explanation:

first you want to find the exact cost of the inspection fee

so you are going to subtract 60 from 95

because if the repair man only worked 3 hours subtracting 60 from 95 will give you the amount they paid minus 30%

add 30% to the 35 and you get 45.5 as the cost of the inspection fee

so subtract 45.5 from 130 and you get 84.5

and now divide 84.5 by 20 aand you have your answer
