The level of water in a draining pool can be modeled with the function d(t)=12(.72)^t, where d is the depth of water, measured in feet, and t is the amount of time it's been draining, measured in days.

(b) Inayah claims that the pool is draining at a rate of 1.36% per hour. Is she correct? Explain.
