How many pounds of dried apples worth $5 per pound should me mixed with how many pounds of dried apricots worth $9 per pound to makel0 pounds of mixture worth $77?
--------------
Equation:
x + y = 10 lbs
5x + 9y = 77
----------------------
5x + 5y = 50
5x + 9y = 77
-----
Subtract and solve for "y":
4y = 27
y = 27/4 = 6 3/4 lbs (amt. of apricots needed)
----
Solve for "x":
x + (27/4) = 40/4
x = 13/4 = 3 1/4 lbs (amt. of apples)
