Bryant’s pool contains 13,000 gallons of water.

The maximum rate at which the city allows pools to be drained is 720 gallons per hour.

Write a function that represents the number of gallons of water left in Bryant’s pool t hours after he starts draining, if he drains the pool at the maximum rate.
