She made a profit of a dime per apple. How many dimes are in $2.20? Then add two more for the apples she ate.

n = # nickels

d = # dimes

q = # quarters

==================

n+d+q=37

d = n-3

q=n+4

substitute d = n-3 and q = n+4 into the first equation, solve for n, then solve for d and q. I think n = 12 but check my thinking.

Post your work if you get stuck.
