Question

Pola Sommers, a massage therapist, needs 4 ounces of a 46% lavender oil solution. She has only 5% and 60% lavender oil solutions available. How many ounces of each should Pola mix to obtain the desired solution?

Answer 1

o represents the amount of 60% oil

4 - o represents the amount of 5% oil

0.60(o) + 0.5(4 - o) = 0.46(4)
