a health food store sells seasoning blends in bulk. One blend contains 20% basil.Sheila wants to add pure basil to some 20% blend to make 16 ounces of her own 30% blend.Let b represent the amount of basil Sheila should add to the 20% blend.
--------------------------------------------
Equation:
basil + basil = basil
0.20(16-b) + 1.00b = 0.30*16
----
Multiply thru by 100 to get:
20*16 - 20b + 100b = 30*16
----
80b = 10*16
--
b = 2 ounces (amt. pure basil needed)
