What about this one guys, I tried setting it up like i was shown on the one similar but i keep getting a negative number.
Kelsey has 32 coins in her pocket, all which are nickels and quarters, If the total value of her change is $4.20, how many nickels and how many quarters does she have?
if 16 of each, total is 480
Each quarter replaced with a nickel drops the total by 20.
So, to lose 60 cents, replace 3 quarters with nickels.
19 nickels, 13 quarters
19*5+13*25 = 420
Too bad you won't show your work ...
