"x" pounds of candy valued at $3.50 per pound is mixed with "y" pounds of candy valued at $4.30 per pound to produce 10 pounds of a mixture selling for $4 per pound. Find "x" and "y", the number of pounds of each type.
--------
Quantity Eq:::: x + y = 10 lbs
Value Eq::::::3.5x+4.3y = 4*10 dollars
------------------------------------------
Multiply thru Quantity Eq by 35
Multiply Value Eq by 10
-------
35x + 35y = 350
35x + 43y = 400
----
Subtract and solve for "y":
8y = 50
y = 6.25 lbs (amt. of $4.30 candy needed)
------
Solve for "x":
x + y = 10
x + 6.25 = 10
x = 3.75 lbs (amt. of $3.50 candy needed)
