You can put this solution on YOUR website! Lupe's mother paid $ 7.40 to buy juice for the 14 members of Lupe's softball team. If a bottle of orange juice costs $.55 and a bottle of apple juice costs $.45, how many of each type did she buy?
---------------------
Equations:
Quantity: r + p = 14 bottles
Value::: 55r+45p = 740
-----------------------------------
Multiply thru the 1st by 55 to get:
55r + 55p = 55*14
55r + 45P = 740
--------------------------
Subtract and solve for "p":
10p = 30
p = 3 (# of bottles of apple juice)
------
Solve for "r":
r + p = 14
r + 3 = 14
r = 11 (# of bottles of orange juice)
