Question

Describe and correct the error in finding the total cost of a $49 meal with 6%sales tax and an 18%tip. Total cost =49+(0.6+0.18)(49). =49+(.77)(49)=$87.22

Answer 1

Explanation:

The original cost of the meal is $49

There was 6% sales tax. This is an additional cost that is charged on the meal meal. The amount of the sales tax can be determined by multiplying the original cost of the meal by 6%

The sales tax becomes 0.06× 49 = $2.94

A tip of 18% was also given. The amount of the tip can be determined by multiplying the original cost of the meal by 18%

The amount of tip becomes 0.18× 49 = $8.82

The error made in finding the total cost was that 0.6 was written instead of 0.06. 0.6 meant that the sales tax was 60% while it was actually 6%.

The correct approach will be

49+(0.06+0.18)(49). =49+(.24)(49)=$60.76
