Question

Clara's family has lunch at a restaurant. The total bill is 67.58. The bill includes 6% tax and 18% tip on the pre-tax amount. How much was the bill before tax and tip.

Answer 1

$54.50

Explanation:

$67.58 after 6% tax and 18% tip

Let x = pretax and pre-tip amount.

The amount of tax is 0.06x.

The amount of tip is 0.18x.

The total amount is x + 0.06x + 0.18x = 1.24x.

The amount after tax and tip is $67.58.

1.24x = 67.58

x = 67.58/1.24

x = 54.5

Answer: $54.50
