Madison makes 30 paper boats and sets them afloat. 20% are eaten by fish and Madison shoots two of the others with flaming arrows. How many boats are left?

How many boats are eaten by fish? ** First find the number of boats eaten by fish: 30 boats * 20% = <<30*20*.01=6>>6 boats
How many boats are left? ** Then subtract the two groups of boats that were destroyed from the original number to find the number left: 30 boats - 6 boats - 2 boats = <<30-6-2=22>>22 boats
