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

Which equation could be used to find the total amount that Sam should pay?

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
