Consider the project in question $1$ with net present value function:

NPV$($i$)=-10-12*(1+$i$)^(-1)+8(12,2)(1+$i$)^(-$t$)$ dt $+6*(1+$i$)^(-12)$

If an investor can borrow and lend at a rate of interest of $20\%$ per annum, the profit or loss at time T $=12$ when the project ends, is

$-7\mathrm{.}8$x$10^16$

$555\mathrm{.}0$

$0\mathrm{.}70$

$55\mathrm{.}5$
