Question

Which customer left the server more money as a tip? Explain.
Customer 1: a 20% tip on a restaurant bill of 30$
Customer 2: a 15% tip on a restaurant bill of $40 after 5% sales tax is added

Answer 1

1. 20% of 35 = (.20)(35) = the tip left
2. 40(.05) = 2.00....40 + 2 = 42.00...the tip is (.15)(42)
can you take it from here ?
