Melanie's food bill at a restaurant is $28.45. the sales tax rate is 6%. if she added 20% of the amount for a tip, what is the total cost of the meal?

$36.19

Step-by-step explanation:

Tip is added before tax.

Tipping 20% of the bill means multiplying 20%, or 0.2, by 28.45:

0.2(28.45) = $5.69

This makes the pre-tax total

28.45+5.69 = 34.14

Adding a 6% tax means taking 100%+6% = 106% of the number;

1.06(34.14) = 36.19

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
