OpenStudy (shaleiah):

yes

OpenStudy (3mar):

With my pleasure! Where are you stuck exactly?

OpenStudy (shaleiah):

Is this the proper formula to find the growth? 821(1+.15)^6?

OpenStudy (3mar):

there are 15% "fewer" fish each month or "more"?

OpenStudy (3mar):

"find the growth? 821(1+.15)^6?" are you going to find the growth or decay!?!?!

OpenStudy (shaleiah):

decay

OpenStudy (shaleiah):

821(1-.15)^6

OpenStudy (3mar):

So That makes sense now!

OpenStudy (shaleiah):

309.64?

OpenStudy (3mar):
