Solve each word problem by using the big ideas above to set up an equation. 1. Bill has 4 times as many quarters as dimes. In all he has $2.20. How many coins of each type does he have? Hint: Let n represent the number of dimes, and so 4n will represent the number of quarters. Then fill-in the table and set up your equation as n(10) + 4n(25) = 220. Notice that the $2.20 is written without the decimal because everything is in cents.
