After three minutes, there are 8.25 gallons of water in the sink. If this pattern continues, how many gallons of water will be in the sink after five minutes?

How many gallons of water will be in the sink after five minutes?
a. 2.75
b. 11
c. 13.75
d. 16.5

Answer 1

After analyzing the pattern of water increase in the kitchen sink, it is determined that after five minutes, there will be 13.75 gallons of water in the sink. The amount increases by 2.75 gallons each minute.

Step-by-step explanation:

The question presents a sequence in which the amount of water in the sink after each minute is growing by a consistent amount. After one minute, there are 2.75 gallons in the sink, which doubles to 5.5 gallons after two minutes, and increases by another 2.75 gallons to 8.25 gallons after three minutes. To find out how many gallons of water will be in the sink after five minutes, continue the pattern of adding 2.75 gallons for each additional minute:

1. After four minutes: 8.25 gallons + 2.75 gallons = 11 gallons.
2. After five minutes: 11 gallons + 2.75 gallons = 13.75 gallons.

Therefore, the correct answer is (c) 13.75 gallons of water in the sink after five minutes.
