A tank can hold a maximum of 400 gallons of water. The volume of water when pumping water into the tank can be determined by the

function f (m) = 12.5m + 25 where m is the number of minutes that the pump is running and f(m) is the volume of gallons of water in the tank. If the tank must maintain a minimum of 25 gallons of water, which inequality represents the domain of this situation?
(Hint: The variable f(m) is like "y" and m is like "x")
0 < m < 400
30 < m < 400
25 < m < 400
0 < m < 30
