Answer:
c. 15 percent
Step-by-step explanation:
From this scenario, we have the following information:
Total investment (cash outflow) = $1,500,000 + $500,000 = $2,000,000
The cash inflow in every of 20 years is $319,522
In excel, the formula is Rate(20,-$2000000,$319522) = 15%
If we do calculation manually, we have to solve this equation:
$2,000,000 = $319,522/(1+r)^1 + $319,522/(1+r)^2+.....+ $319,522/(1+r)^20
in which r is expected rate of return.
You can see both 2 calculation in excel attached
