The equations below show the total amount of water in gallons, y, that has flowed through two different types of shower heads after x minutes of use.
Type A: y = 1.25x
Type B: y = 2.50x
Based on these equations, which of the following statements is a correct comparison?
A) For each minute of use, the amount of water that flowed through Type B is twice the amount that flowed through Type A.
B) For each minute of use, the amount of water that flowed through Type A is twice the amount that flowed through Type B.
C) The amount of water that flowed through Type A per minute increased at a faster rate than the amount of water that flowed through Type B per minute.
D) The amount of water that flowed through Type B per minute increased at a faster rate than the amount of water that flowed through Type A per minute.
