Q:
# A 20-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?18273345

Accepted Solution

A:

divide size of candle by number of hours

to find the rate it burns:

20 ounce / 60 hours = 1/3 ounce per hour

divide 9 ounces by 1/3 ounce per hour to find total time:

9 / 1/3 = 27 hours

to find the rate it burns:

20 ounce / 60 hours = 1/3 ounce per hour

divide 9 ounces by 1/3 ounce per hour to find total time:

9 / 1/3 = 27 hours
