6) There were 5000 gallons in a water tank at t = 0 hours. Water is being added to the tank at a rate of f(t) = 35(1.25)^t gallons per hour, t_>0. At the same time, water is leaking out of the tank at a rate of
gallons per hour.
g(t)=10e^0.05t.
Find the number of gallons in the tank at t = 10. Solve algebraically.
