The fundraising group collected the quarters from the school's wishing well. The group arranged the quarters into 8 piles and of 20 quarters. Let q be the number of quarters in the well. How much money in dollars did the group collect?
8•20=q. Multiply the number of piles by the number of quarters in each pile: 8•20=160, there were 160 quarters. Now to find how much they made multiply the number of quarters by how much 1 quarter is: 160•.25=40 they made $40 :)
