A student makes a $9.25 purchase at the bookstore with a $20 bill. The store has no bills and gives the change in quarters and fifty-cent pieces. There are 30 coins in all. How many of each kind are there?

How many quarters are there in the change___?

How many fifty-cent pieces are there in the change___?

1 answer

20.00 - 9.25 = 10.75

25 q + 50 f = 1075
q + f = 30

q + 2 f = 43 divided top one by 25
q + 1 f = 30
------------ subtract
f = 13
you can do it now
