Expert Solution

We know that,

Future Value = Amount *(1+ monthly rate)^(end year - current year) + Amount *(1+ monthly rate)^(end year - current year) +Amount *(1+ monthly rate)^(end year - current year) +Amount *(1+ monthly rate)^(end year - current year) +Amount *(1+ monthly rate)^(end year - current year) +............ + Amount *(1+ monthly rate)^(end year - current year)

Monthly Rate = 0.6%

Amount = 180

Number of payments = 12*40 = 480

Future Value = 180 * { (1+ 0.006)^(480-1) + (1+ 0.006)^(480-2) + (1+ 0.006)^(480-3)+ (1+ 0.006)^(480-4)+(1+ 0.006)^(480-5)+(1+ 0.006)^(480-6)+ ........... (1+ 0.006)^(480-480)

Future Value = 499848.86 Answer
