2) Here we use pmt formulae in excel to find the payment monthly or weekly

=pmt(rate,nper,pv,fv,type)

a)4.5% monthly

Rate= interest rate based on compounding frequency=4.5%/12(since monthly compounding)

Nper=period=30*12(since it is for 30 years and monthly compounding)

Pv=500000

Fv=0

Type=0

=pmt(4.5%/12,30*12,500000,0,0)=2533

b)4.5% weekly

Rate= interest rate based on compounding frequency=4.5%/52(since weekly compounding)

Nper=period=30*52(since it is for 30 years and weekly compounding)

Pv=500000

Fv=0

Type=0

=pmt(4.5%/52,30*52,500000,0,0)=584

3) We can find using pv formulae in excel

=pv(rate,nper,pmt,fv,type)

a)rate is 12%

=pv(12%/12,60,-150,0,0)=6743.26

b)rate is 15%

=pv(15%/12,60,-150,0,0)=6305.19
