Answer :
Answer:
D. None of the above (14.28 minutes)
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:
[tex]G=\frac{7}{2}X[/tex]Then, if the tub can hold 50 gallons, we can replace G by 50 as follows:
[tex]50=\frac{7}{2}X[/tex]So, the number of minutes that the tub will take to fill can be found if we solve the equation for X. Then:
[tex]\begin{gathered} 50\cdot2=\frac{7}{2}X\cdot2 \\ 100=7X \\ \frac{100}{7}=\frac{7X}{7} \\ 14.28=X \end{gathered}[/tex]Therefore, the correct answer is 14.28 minutes.
