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:

A family eats out at a restaurant and the total for their meals is = $73.89.

They also pay sales tax of 5.8%, so let the percentage of tip = x %

Then the total extra payment they made = (5.8+x) %

Total payment = 73.89 + (5.8+x) % of 73.89

Total payment made is = $ 93,

73.89 + (5.8+x) % of 73.89 = 93

(5.8+x) % of 73.89 = 19.11

Solving this we get,

73.89(5.8+x)=1911

5.8 + x = 25.86

x = 20.06%

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

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
