Ben plans to make the following deposits into his savings account: $350 in 24 months, $500 in 30 months and $750 in 42 months. He earns interest at 6% p.a. compounded half-yearly. 1. Ben chooses to use the following equation to calculate his account balance in 5 years. FV = 350 * (1 + 0.03)": +500 + (1 + 0.03)^2 + 750 *(1 + 0403)", Calculate the following variables in the above equation. The variables may or may not be the same value. Show your answer as an integer (positive or negative). Do not include units like "years" or "months" (number only). Do not use comma separators. For example, 123456 would be the correct format. n = (0.5 mark) n2= (0.5 mark) n3= (0.5 mark) 2. Ben chooses to use the following equation to calculate his account balance in 6 years. FV = 350 + (1 + i) + + 500*(1 + i)3.5 + 750 + (1 + i) 2.5 Calculate the following variable in the above equation: Round your answer to the nearest 0.001% (3dp). Do not include the % symbol. Do not use comma separators. For example, if your answer in decimal is 0.123456, 12.346 would be the correct format. i= % (0.5 mark)
