Question

One species of fish in a fishery had an initial population of 255 fish and grew by 25 fish each season. A second species that was being overfished started with an initial population of 450 fish, and then decreased by 40 fish each season. Assuming a linear change, write equations for the populations of each species. When will the two populations have the same amount of fish? After how many seasons will the second species be eliminated?

Answer 1

they intersect at 3.5 seasons, 312 fish. the second gets elimed at 11 seasons

Explanation:

equations:

first:

amount of fish = 225 + 25*season

second:

amount of fish = 450 - 40*season
