A pool must be drained to complete repairs at the end of summer. The volume of water in the pool, in gallons, is modeled by the linear function w(t) = 483 - 23t, where t represents the time in hours.
a. Determine and interpret the domain of the function.
b. 0 ≤ t ≤ 21; the volume of water decreases from 21 to 0 gallons
c. 0 ≤ t ≤ 21; the pool will drain from hours 0 to 21
d. 0 ≤ t < 483; the volume of water decreases from 483 to 0 gallons
e. 0 ≤ t < 483; the pool will drain from hours 0 to 483
