sterile fruit flies are used in an experiment where the proportion that survives at least t days is given by e^-0.15t. If the experiment begins with 200 fruit flies and are added at the rate of 5 per hour, how many flies are present 14 days after the start of the experiment.
Please help!

thanks i didn't think to make an equation. Do you think though that instead of 5t it would be 120 t because t is in days and its 5 flies every hour?
idk:D

I'm pretty sure its 5t because after each hour 5 flies are added. 1 hour = 5 flies, 2 hours = 10 fies, ect. So its 5t.
