Oh, it says compound interest.
M = P( 1 + i )^n
Let's say that I have $1000.00 to invest for 3 years at rate of 5% compound interest.
M = 1000 (1 + 0.05)^3 = $1157.62.
You can see that my $1000.00 is worth $1157.62.

so 1157.2=62 is the final answer? o.0

Also, I don't answer notifications. Next time don't tag me, just send me a few messages and get on the chat. I also recommend leaving a note on my profile to grab my attention.
