You can put this solution on YOUR website! Two malts and two sodas cost $1.30. three malts and one soda cost $1.45. Find the cost of one malt and one soda.
--------------------------------
EQUATIONS:
2m + 2s = 130
3m + s = 145
------------------
Multiply the 2nd equation by 2 and subtract from the 1st to solve for "m":
-4m = -160
m = 40
----------------
Substitute into 3m+x = 145 to solve for "s":
3*40 + s = 145
s = 25
--------------------
Check answers in 2m+2s = 130
2*40 + 2*25 = 130
80 + 50 = 130
130 = 130
===============
Final Answer:
40 cents (cost of malt)
25 cents (cost of soda)
