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 $73.89\times0.058 = 73.89\times\frac{58}{1000}=4.28562\approx4.29$.

Step2: Calculate the total cost of meal and tax

The total cost of the meal and tax is $73.89 + 4.29=78.18$.

Step3: Calculate the amount of the tip

The family left a total of $93. So the tip amount is $93 - 78.18 = 14.82$.

Step4: 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.
