Solution



Given:
    • The cost, in dollars, for and appliance repair at a certain company is 1.2p + 20h, where p is the wholesale price of the parts, in dollars, and h is the number of hours it takes to repair the appliance

To find:
    • The cost of repairing an appliance if the wholesale price of the parts is $15 and it takes 2 hours to repair it

Approach and Working:
The wholesale appliance takes 2 hours to repair and price of the parts is $15
    • Total cost of repairing = 1.2 * 15 + 20 * 2 = 18 + 40 = 58

Hence, the correct answer is option E

Answer: E

Straight question. We need to put the values into the given formula.

1.2p + 20h

= 1.2*15 + 20*2
= 18 + 40
= 58

Thus the best answer is E.

Cost of repair at (15,2)= 1.2p + 20h=1.2*15+20*2=18+40=$58

Ans. (E)

We are given that p = 15 and h = 2, so the total cost of repairing the appliance is 1.2(15) + 20(2) = 18 + 40 = 58 dollars.

Answer: E
