Question

Tropical Fish - The total number of fish will depend on the size of a pond or aquarium. At the Reading Mandarin Restaurant a total of 90 tropical fish were placed in an aquarium. For the next 12 months the total number of fish could be predicted by the equation

P(x) = 90(I + 1.5x)/1 - 0.5x

where P is the number of fish and x is the number of months since the fish were placed in the aquarium



One month after the fish are first placed in the aquarium, what is the total number of fish?



Three months after the fish are first placed in the aquarium, what is the total number of fish?
