1). i'm still lost. i get that p(t)= 5
but what about the -0.2t ? do i place the 5 in and multiply?

which if i did i would get 32e^{-0.2t} =86.98
? 86.98 = 5 ?

what are the steps for this problem?


2.)

so after the 3rd year the investment tripled?

i just take a=8000 and mult. that by 3??

what do you mean it is a G.P? there wasn't a formula that i needed to use?
