The question are...


An web developer has found a bug on one of URL on the web that he assume he can fix it to make more better 25 % on that URL to go much better than it was. The URL company offer the web developer to try fix it with 2 way of payment, it is pay all of it now for 100 million or pay every year 20 million for the first 7 years and the rest 6 million for the next 8 years. Which payment that the web developer choose if he analize it with 15 % of interest ?


Answer :

*> The first method was P1 = 100 million
*> The second method was,,

P2 = 20 million (P/A, 15%, 7) + 6 million (P/A, 15%, 8) (P/F, 15%, 7)
= 20 million (4,160) + 6 million (4,487) (0,3759)
= 83,20 million + 10,120 million
= 93,320 million

So, because the first alternative was bigger then the second one,, the web developer choose the first one.
