Question

Sam wants to leave an 18% tip for his dinner. The bill is for $23.50.

Answer 1

Divide the % of tax u want to leave by 100 then multiply that by the total. that will give u the $ of tax. if u add that on to the sub total that will give u the final total.

Example:
18/100= .18
.18x$23.50= $4.23 (this is the tax in $
$23.50+$4.23= $27.73
