You went to your bank and got 5 rolls of pennies, 4 rolls of nickles, 3 rolls of dimes, 2 rolls of quarters, and 1 roll of half dollars. how much did you pay the bank?

Pennies come in 50 cent rolls ... 5 rolls = 5 * 0.50 = 2.50

nickels come in $ 2 rolls ... 4 rolls = 4 * 2 = 8.00

dimes come in $ 5 rolls ... 3 rolls = 3 * 5 = 15.00

quarters come in $ 10 rolls ... 2 rolls = 20.00

half dollars come in $ 10 rolls ... 1 * 10 = 10.00

u owe the bank : 2.50 + 8 + 15 + 20 + 10 = $ 55.50
