Question

Sierra left $4.50 as a tip for a waiter. This was 18% of the bill before the tip. How much was her total bill before the tip?

Answer 1

answer: $25


since 4.50/18% = 4.50/0.18 = 25

Answer 2

$25

Explanation:

Let x = bill

Since 18% of the bill is 4.5, we multiply x by 0.18

0.18x = 4.5

Divide both sides by 0.18

0.18x/0.18 = 4.5/0.18

x = 25
