The principal repaid in the second payment is 1414 = X –(60,000 – 1400)j. Substituting X = 1400 + 60,000j from the first equation gives 1414 = 1400 + 60,000j – 58,600j or 14 = 1400j and thus j = 0.01 and X = 2000. Let n be the number of payments. Then <math display = "block">60000 = 2000 a_{\overline{n}|0.01}</math> an...") | Nov 19'23 at 0:53 | +704 |
