Recent studies show that the number of three-legged frogs in a particular area is increasing due to exposure to chemical pollutants. The first set of data reported in 2000 estimates a population of 5000 three-legged frogs. Statistics show an annual increase of 15%. Let GN denote the number of three-legged frogs projected to inhabit this area in the year 2000 + N.Give an explicit formula for GN.

A. GN = 5000 ? (1.5)N B. GN = N ? (1.15)5000 C. GN = 5000 ? (N)1.15 D. GN = N ? (5000)1.5 E. GN = 5000 ? (1.15)N
