Question

Jamal wants to buy a gift for a friend. He opened his piggy bank to find 3 one-dollar bills, 4 five-dollar bills, 7 ten-dollar bills, 15 quarters, 12 dimes, 34 nickels, and 64 pennies. If he wants to keep $10.00 in cash for himself and buy a gift with the rest of the money, how much money can he spend?

Answer 1

Jamal can spend $90.29 to buy a gift for a friend.

Explanation:

We have to sum all bills and coins denomination separately, then sum all the money and subtract $10, to know how much he can spend:

`3*1one-dollar=3\\4*5five-dollar=20\\7*10ten-dollar=70\\15*0.25quarter=3.75\\12*0.10dime=1.20\\34*0.05nickel=1.70\\64*0.01pennie=0.64`

This sum:

`Money=100.29`

Then subtracting the $10.00 we have:

`100.29-10.00=90.29`

Jamal can spend $90.29 to buy a gift for a friend.
