Question 354094
How many ounces of vegetable oil containing 8% saturated fats must be added to 14 ounces containing 20% saturated fats to make a salad dressing containing 15% saturated fats?
-----------------------
Equation:
fat + fat = fat
0.08x + 0.20*14 = 0.15(x+14)
-----------
Multiply thru by 100 to get:
8x + 20*14 = 15x + 15*14
----------
7x = 5*14
x = 10 (amt of 8% oil needed in the mixture)
