a) The linear function that models the amount of water after t minutes is given by:

V(t) = 200 + 12t

b) It takes 92 minutes to completely fill the pond.

Item a:

  • Initially, the pond contains 200 gal of water, that is, the linear function has a y-intercept of 200.
  • Filled at a rate of 12 gallons per minute, thus the linear function has a slope of 12.

Then, the function is:

V(t) = 200 + 12t

Item b:

It takes t minutes to fill the pond, t is found for which:

V(t) = 1304

Then

200 + 12t = 1304

12t = 1104

t = \frac{1104}{12}

t = 92

It takes 92 minutes to completely fill the pond.
