Courtney Owen · Answer 1

First find the percent of the sales tax added with the tip amount, which is 20%

15% + 5% = 20%

and the percent amount to the original amount, so

20% + 100% = 120%

$18=120% of original amount (12/10 is the same thing as 120%), so

18/12*10=$15 = price of meal before tax and tip!
