Dedre has the following obligations: R2 000,00 due at the end of three years; and R4 800,00 due at the end of five years. The interest rate charged on all amounts is 16% per year, compounded quarterly. What two equal payments, one at the end of two years and the other at the end of six years, will replace these obligations? This is represented by the following timeline: R2000 R4 800 0 5 6 7 years RX RX 16% per year, compounded quarterly The value of X has to be determined. Use year six as the settlement date. The equation that describes this situation is Select one: a. X x 1,04 + X = 2000 x 1.04 +4800 x 1,04 1x4 b. 2X = 2000 (1 + 0.16) 3x4 + 4800(1+0.16) 4 c. 2X(1 +0,4)4x4 = 2000(1+0,4)2 +4800(1+0.4) 16 d. X(1 + 0,16) 6+ X = 2000 (1 + 0.16) + 4800(1 + 0,04)* 2 -00
