Answer
Explanation:
Step1: Calculate the amount of sales - tax
The sales - tax rate is 5.8% or 0.058. The cost of the meal is $73.89. So the sales - tax amount is $73.89\times0.058 = 73.89\times\frac{5.8}{100}=4.28562\approx4.29$.
Step2: Calculate the total amount of tip
The total amount paid is $93$, and the cost of the meal plus sales - tax is $73.89 + 4.29=78.18$. So the tip amount is $93−78.18 = 14.82$.
Step3: Calculate the tip percentage
The tip percentage is $\frac{14.82}{73.89}\times100%\approx20%$.
Answer:
C. They left a 20% tip, so the service was probably above average.
