A man buys a machine under the deal, that he pays 10% of the machine's price as downpayment, and repays the rest of the cost plus 13% simple interest ( on the price of the machine) within 1 year. The amount of disbursements is immaterial, only the net payable matters. If the entire payment is not made by one year of the purchase, the net payable increases due to a fixed increase of the interest rate, which rises as 3% per year (following the first year). If the man managed to pay off the entire payable (including the down payment) amounting to $10,500 only by the third year, what was the initial cost of the machine? A) $9,051.72 B) $8,000.00 C) $8,823.52 D) $9292.03

@Xmoses1

OpenStudy (xmoses1):

I think that it is C

OpenStudy (anonymous):

@Xmoses1 tell me is it 13% + 3% for 3 years OR 16% together for 3 years??

OpenStudy (xmoses1):

Well i went with 13% + 3% for 3 years

OpenStudy (xmoses1):

16% compounded annually would get you a different answer

OpenStudy (anonymous):

i'll try to solve it backwards... will tell u tommorrow

OpenStudy (xmoses1):

Ok let me know what you get

OpenStudy (anonymous):

let the cost be X: 0.1X + 3[13% 0f (0.9X)] + 3[3% of (0.9X)] + 0.9X = 10,500 is it the right equation??

OpenStudy (anonymous):
