Answer:
The present value is $3,991,855.88
Explanation:
The interest given can be converted into effective annual rate using the below formula:
EAR = [(1 +stated rate/no. of compounding periods) ^no. of compounding periods - 1]* 100
EAR=(1+5%/12)^12-1*100
    =5.12%
FV of downpayment=PV*(1+r)^N
                 =$1000000*(1+5.12%)^10
                  =$ 1,647,606.60 Â
Future of an ordinary annuity=A((1+r)^N-1/r
                        =$15000*((1+5.12%/120)^10*12-1))/5.12%/120
                        =$2,344,249.28
Total present values=2344249.28+1,647,606.60 Â
                 =$3,991,855.88
