Question 1052070: You spend $27 on seven bags of candy to throw why you participate in a parade. The bags cost either five dollars or three dollars. How many bags of each amount did you purchase? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! You spend $27 on seven bags of candy to throw why you participate in a parade. The bags cost either five dollars or three dollars. How many bags of each amount did you purchase?
-------
Quantity Eq:: f + t = 7 bags
Value Eq::: 5f + 3t = 27 dollars
-----------------------------------
Modify for elimination::
5f + 5t = 5*7
5f + 3t = 27
---------
Subtract and solve for "t"::
2t = 8
t = 4 (# of $3 bags)
f = 7-4 = 3 (# of $5 bags)
