A family eats out at a restaurant and the total for their meals is $73.89. They also pay sales tax of 5.8% and leave a tip for their server. If the family leaves a total of $93, which of the following might be a description of the service they received?
Answer
A
They left a 10% tip, so the service was probably below average.
B
They left a 15% tip, so the service was probably average.
C
They left a 20% tip, so the service was probably above average.
D
They left a 25% tip, so the service was probably outstanding.
Explanation
The 5.8% sales tax on $73.89 is about $4.29, making the bill with tax about $78.18. Subtracting that from the $93 total leaves about $14.82 for the tip. That is about 20% of the $73.89 meal cost, so the best choice is that they left a 20% tip and the service was probably above average.
