A landscaper puts 8 fish into new pond. The numbers of fish triple over a period of time. Write a function f(x) to model the number of fish in the pond after x months

answer. d.289 hope that

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
