9 quarters, 7 dimes, & 5 nickels
A quarter is $0.25, a dime is $0.10, & a nickel is $0.05
So we just need to multiply the values & then add them up.
9 quarters is $2.25, 7 dimes is $0.70, & 5 nickels are $0.25
When you add them up, the total value of Jack's change is $3.20
He's really close, but Jack doesn't have enough money
