Let t=50
y=30(2.7)^0.004t
y=30(2.7)^0.004(50)
y=30(2.7)^.2
Need help with proper technique for using TI83 to calculate.
Thanks

I don't have a TI , mine is an old SHARP.
But most work pretty well the same way.
On mine I would type:
30
x
2.7
y^{x} , or some key that resembles a power
.2
± , to make it negative
=
to get 24.59509486
