A20-ounce candle is expected to burn for 60 hours. a 12-ounce candle is expected to burn for 36 hours. assuming the variables are directly related, how many hours would a 9-ounce candle be expected to burn? 18 27 33 45

B. 27.

Step-by-step explanation:

We have been given that a 20-ounce candle is expected to burn for 60 hours. A 12-ounce candle is expected to burn for 36 hours.

We know that a direct proportional equation is in form , where k represents constant of proportionality.

Let is find value of k by substituting and in above equation as:

The equation represents our given direct proportional relation.

Now, we will substitute to solve for y as:

Therefore, a 9-ounce candle would be expected to burn for 27 hours and option B is the correct choice.

answer:     true
