Question

When full, the volume of water in a koi pond is 662 gallons. Due to a leak in the pond, the volume of water in the pond is decreasing at a rate of 0.9% per minute. If the amount of water in the pond continues to decrease at this rate, which function represents the amount of water in the pond after t minutes?
V(t) = 662(0.009)t
V(t) = 662(1.009)t
V(t) = (662)(0.991)t
V(t) = 662(0.991)t
