The city council has decided to add a 0.3% tax on motel and hotel rooms. If a traveler spends the night in a motel room that costs $55 before taxes, how much will the city receive in taxes from him?
I am studying for a exam, would you also know a good website for math review? thankyou

Multiply the pretax cost by the tax rate to get the tax collected. In the given case,
pretax cost = $55
tax rate = 0.3% = 0.3/100 = 0.003
Tax collected = $55*0.003 = $0.17
