Question

Mary purchased 4 tires by mail order. She paid ​$54.90 per tire plus​ $6.50 per tire for shipping and handling. There is no sales​ tax, because the tires were purchased out of state. She also had to pay​ $8.34 per tire for mounting and balancing. At a local​ store, Mary's total for the 4 tires with mounting and balancing would be ​$332 plus 8​% sales tax. How much did Mary save by purchasing the tires through the​ mail? Mary saved ​$ nothing on the purchase of 4 tires.

Answer 1

79.6 dollars saved

Explanation:

Mail

4 times 54.90 equals 219.6

4 times 6.50 equals 26

4 times 8.34 equals 33.36

219.6 + 26 + 33.36 = 278.96

Local store

332 times .08 equals 26.56

332 + 26.56 = 358.56

Difference

358.56 - 278.96 = 79.6
