Answer

Explanation:

Step1: Calculate sales - tax amount

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=$4.28562\approx$4.29$.

Step2: Calculate the total amount of tip

The total amount paid is $93 and the sum of the meal cost and 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
