Math Problem Statement
Frogs have been dying like flies at the Enormous State University (ESU) campus! Each year, the pledge class of the Epsilon Delta fraternity is instructed to tag all the frogs residing on the ESU campus. Two years ago (t = 0) they managed to tag all 54,000 of them (with little Epsilon Delta Fraternity tags). This year's pledge class discovered that all the tags had fallen off, and they wound up tagging a total of 36,000 frogs. (a) Find an exponential model for the frog population, with t in years. f(t) =
Correct: Your answer is correct. (b) Assuming exponential population decrease and that all this year's tags fall off, how many tags should Epsilon Delta order for next year's pledge class? (Round your answer to the nearest integer.)
Incorrect: Your answer is incorrect. tags
