Joe has a total of 14 pennies, dimes and quarters in his pocket, which total $1.52. The number of dimes and quarters combined is equal to the number of pennies. How many of each coin does Joe have?

OpenStudy (anonymous):

well first you know that there has to be 7 pennies, right? Since it says that the number of dimes and quarters equal the number of pennies, and they add up to 14.

I think I know the answer

OpenStudy (anonymous):

go on ahead dude.

OpenStudy (anonymous):

There are 5 quarters and 2 dimes

OpenStudy (anonymous):

Subtract .07 from 1.52 to get 1.45

OpenStudy (anonymous):

5 quarters = $1.25

OpenStudy (anonymous):

2 dimes = $0.20

OpenStudy (anonymous):

I agree. :)

OpenStudy (anonymous):

You add all three up to get $1.52

OpenStudy (anonymous):
