Question

Peter took one of his friends out to lunch. The lunches cost $100 plus he

paid 12% in sales tax. If Peter left a 18% tip on the meal cost ($100), how
much did he pay in total, including sales tax and tip?

Answer 1

Tax = $12 Tip = $18 Total Cost = $130

Explanation:

tax = tax percentage x amount

0.12 x 100 = 12

tip = tip percentage x amount

0.18 x 100 = 18

The Total Cost

total cost = cost + tax + tip

100 + 12 + 18

Add them up and it would be

$130
