Alex stocks up for winter.
He buys 36 cans of vegetables he payes 80 cents per can for tomatoes and 40 cents per can for corn for a total cost of 20.80.
how many cans of corn does he buy?
-----
Quantity Eq:: t + c = 36
Value Eq::: 80t +40c = 2080 cents
------------------------------------------
Multiply thru by 80 to get:
80t + 80c = 80*36
---
Subtract that from the Value Eq and solve for "c":
-40c = -800
c = 20 (# of can of corn bought)
