Answer:
D. None of the above (14.28 minutes)
Step-by-step explanation:
If the rate is 7 gallons every 2 minutes, we can calculate the number of gallons in the tub after X minutes using the following equation:
Then, if the tub can hold 50 gallons, we can replace G by 50 as follows:
So, the number of minutes that the tub will take to fill can be found if we solve the equation for X. Then:
Therefore, the correct answer is 14.28 minutes.
