I don't understand the part b.

jhonyy9:

\[P = a * b^{t}\] so from this above wrote equation how you calcule the t ?

jhonyy9:

like a first step divide both sides by a so in this way what will get ?

Macho14:

p/a=b^t/a?

yes in this way is correct so now using logarithm how you calcule the t ?

jhonyy9:

do you know this ? \[\log_{a} a = 1\]

Macho14:

yes. in(p/a)/in(b)=t right?

jhonyy9:

yes

Macho14:

what next then?

jhonyy9:

substitute these details inside your given formula and calcule the t value

Macho14:

but what about p? is p = 49600?

jhonyy9:

exactly
