Best ResponseYou've already chosen the best response.0Plug in the known info to find k in the formula. Then rewrite the equation using the value of k you found and solve for P when t = 15. A is the starting amount P is the amount at t time \(\large P = Ae^{kt} \) \(\large 4800 = 4000e^{k \times 5} \) Find k.

Best ResponseYou've already chosen the best response.0Multiply 400 times 13 hours (400 bacteria every 2 hours), then add the 4000 in addition to it I got 9200 ...you have to round that though, which would be 9000 I believe.
