Answer:
A
Step-by-step explanation:
22 successes out of a group of 40 means 22/40 were good. Now, simplify 22/40. Both can be divided by 2.

Elio is right in assuming the relationship between the height and the hours it burns is proportional.
Find the unit rate
14 ÷ 8 = 1.75 cm/h
Divide
21 ÷ 1.75 = 12
You can set this up as an algebraic equation to check the answer.
If the candle is 21 cm tall, it will burn for 12 hours.
