Question 43886
For a product to be labeled orange juice, a state agency requires that at least 80% of the drink be real orange juice.  How many ounces of artificial flavors can be added to 32 oz of real orange juice if the drink is to be labeled orange juice?

Start: 32 oz of 100% orange juice
Add:   x oz of 0% orange juice
End up with: "32+x" oz of 80% orange juice

EQUATION:
 oj + oj = oj

32 +0= .80(32+x)
32 = 25.6 + 0.8x
0.8x=6.4
x=8 oz(amount of artificial flavor added)
Cheers,
