Question

A small business that makes candles uses a proportional amount of essential oil and wax. For 132 ounces of wax, they use 11 ounces of essential oil.

How many ounces of essential oil is needed for 648 ounces of wax?

A. 54 ounces
B. 58.9 ounces
C. 121 ounces
D. 15.9 ounces

Answer 1

Answer: A - 54 ounces

Explanation:

132 divided by 11 ounces = 12

First, you need to figure out the dividend that is giving you the wax-to-oil ratio. Since that is 12, we will divide the new amount of wax by that.

648 divided by 12 = 54

Hope this helps.

Answer 2

A

Explanation:

By proportion, ounces of essential oil for 648 ounces of wax

= 11 * 648/132

= 7128/132

= 54 ounces.
