Question 977470: Need help on how to solve these problems. Please include steps on how to solve. Thank you.
A bathtub is being drained. Since it is an ordinary tub, it can be modeled by the function
V(t) = -15t + 45 where V(t) is the volume of the tub in gallons and t is the time that has passed in minutes. V(T) = -20T + 50 where v(T) is the volume of the tub in gallons and T is the time that has passed. Which tub will drain faster?
Based on the function V(t) = -15t + 45, when will the tub be half full?
