Diego wants to have $10000 in his bank account in 10 years. He plans to make the following deposits into his bank account. $2000 today, $3000 in 5 years and $X in 7 years. The interest rate is 6% p.a. compounded half-yearly. Which of the following equations can be used to find $X? (There may be more than one correct answer. You will lose marks by choosing a wrong answer. The minimum mark for the question is zero.) Select one or more: a. None of the equations can be used to find $X. b. 2000* (1.03)20 + 3000* (1.03)10 + X *(1.036 = 10000 c. X = 10000 2000 * (1.03)20 3000 * (1.03)10 d. 2000 + 3000 * (1.06) 5 + X * (1.06)-7 = 10000(1.06)-10 e. 2000* (1.06)10 + 3000* (1.06) 5 + X * (1.06)3 = 10000 f. 2000 + 3000 * (1.03)-10 + X *(1.03) -14 = 10000(1.03)-20
