a vending machine sells chips at $0.55 and candy at $0.75. Last month, the vending machine yielded $170.00 with the sale of 260 items. How many packages of chips were sold last month?
------------
Equations:
h + c = 260 items
55h+75c = 17000 cents
---------------------------
Modify:
75h + 75c = 75*260
55h + 75c = 17000
--------------------
20h = 2500
# of packages of chips = h = 125
