Question

Ingram called Verizon to argue about his bill. He was paying $95.26 monthly but he argued the new bill down to $78.17. What was the percent decrease in the bill? If Ingram values his time at $25 per hour and the phone call lasted 45 minutes, was the call worth his time?

Answer 1

Explanation:

((95.26 - 78.17) / 78.17)x100

21.86260714% percentage decrease

The phone call was worth his time

Answer 2

Explanation:

He was paying $95.26 monthly but he argued the new bill down to $78.17. The amount by which the bill was decreased is

95.26 - 78.17 = $17.09

Therefore, the percent decrease in the bill is

17.09/95.26 × 100 = 17.94%

60 minutes = 1 hour

45 minutes = 45/60 = 0.75hour

If Ingram values his time at $25 per hour, then the cost of 0.75 hour is

0.75 × 25 = $18.75

The call was worth the time
