Answer 2

I think the second one.

Answer 3

the model that has been used is

\[f(t) = a( 1 + \frac{r}{100})^t\]

a = initial quantity, r is the growth factor and t is time

you have been given

\[f(t) = 1(1 + 0.4)^t\]

the growth model in this question is the compound interest formula.

so compare the 2 to ifentify a and r
