Best Answer

He has 12 dollars and five quarters.

Let X represent the number of dollar bills he has and Y represent the number of quarters he has. From the information given, we know the following:

X=Y+7

AND

X+.25Y=13.25

Solve for X and Y.

Using the value of X from the first equation in the second equation, we get:

(Y+7)+.25Y=13.25

1.25Y+7=13.25

1.25Y=13.25-7=6.25

Y=6.25/1.25=5

Plugging 5 in for Y in the first equation gives us X=5+7=12.
