Afamily 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? 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.

C. They left a 20% tip, so the service was probably above average.

Step-by-step explanation:

Here, the cost of their meal = $ 73.89

Sales tax = 5.8 %

Now, let the percentage of tip = x %

Thus, the total extra payment they did = (5.8+x) %

⇒ Their total payment = 73.89 + (5.8+x) % of 73.89

According to the question,

Total payment = $ 93,

⇒  73.89 + (5.8+x) % of 73.89 = 93

⇒  (5.8+x) % of 73.89 = 19.11

⇒  

⇒ 73.89(5.8+x)=1911

⇒ 5.8 + x = 25.8627689809

⇒ x = 20.0627689809% ≈ 20%

Hence, they paid approximately 20% of tip in the meal,

⇒ The service was probably above average.

⇒ Option C is correct.
