To solve this you can draw 20 little circles. Then start with pennies and then add nickels. You should come out with 13 pennies and 5 nickels

5n+p=48
n+p=20
subtract
4n=28
divide
n=7
n+p=20
7+p=20
p=13
7*5+13=48
The new tutor's answer 5*5+13=38 not $.48 and has only 18 not 20 required coins
BTW There is no reason to make things harder by using decimals.
We are dealing with cents which can be written $.01 or 1
Why make things harder?

Let number of nickels be N Then number of pennies = 20 - N Value equation: .05N + .01(20 - N) = .48 .05N + .2 - .01N = .48 .05N - .01N = .48 - .2 .04N = .28 N, or number of nickels = , or You should be able to find the number of pennies.
