These 20 problems build multistep percent reasoning from standard 7.RP.A.3: sales tax, tips, markups and markdowns, discounts, commission, fees and simple interest I = Prt.
The first six problems use one percent step. Later problems chain several steps, compare two offers, or work backward. Round money to the nearest cent at the end only.
