Jenn is saving up money to buy a bike. She has 5 jars full of quarters. Each jar can hold 160 quarters. If the bike costs 180 dollars, how much money will she have left over after buying it?
Jenn has 5 * 160 = <<5*160=800>>800 quarters.
The quarters are worth 800 * 0.25 = <<800*0.25=200>>200 dollars.
After buying the bike she will have 200 - 180 = <<200-180=20>>20 dollars left.
