Linds has some dimes, nickels,and quaters in her purse. The total value of these coins is $2.55. she has three times as many dimes as quarters. She has three more nickels than quarters. How many coins of each type does she have?
--------------
q = # of quarters, etc
d = 3q
n = q + 3
--------------
25q + 10d + 5n = 255
25q + 10(3q) + 5(q+3) = 255
60q + 15 = 255
60q = 240
q = 4
d = 12
n = 7
