Step by Step N = 36 (3 years = 36 months)

N = 36 (3 years = 36 months)

Step by Step N = 36 I% = 7 (The interest rate is 7% )

N = 36

I% = 7 (The interest rate is 7% )

Step by Step N = 36 I% = 7 PV = $200,000 – $150,000 = $50,000 The prize money

N = 36

I% = 7

PV = $200,000 – $150,000

= $50,000

Step by Step N = 36 I% = 7 PV = $ 50,000

N = 36

I% = 7

PV = $ 50,000

Step by Step N = 36 I% = 7 PV = $ 50,000 FV = 0 (the loan will be repaid after 3 years)

N = 36

I% = 7

PV = $ 50,000

FV = 0 (the loan will be repaid after 3 years)

Step by Step N = 36 I% = 7 PV = $ 50,000 FV = 0 P/Y = 12 (pay monthly)

N = 36

I% = 7

PV = $ 50,000

FV = 0

P/Y = 12 (pay monthly)

Step by Step N = 36 I% = 7 PV = $ 50,000 FV = 0 P/Y = 12 C/Y = 12 (compound monthly)

N = 36

I% = 7

PV = $ 50,000

FV = 0

P/Y = 12

C/Y = 12 (compound monthly)

Step by Step N = 36 I% = 7 PV = $ 50,000 FV = 0 P/Y = 12 C/Y = 12 And move the cursor to the PMT and press [alpha] [enter] to solve for the monthly payment.

N = 36

I% = 7

PV = $ 50,000

FV = 0

P/Y = 12

C/Y = 12

Step by Step N = 36 I% = 7 PV = $ 50,000 FV = 0 P/Y = 12 C/Y = 12 PMT = - $1543.85

N = 36

I% = 7

PV = $ 50,000

FV = 0

P/Y = 12

C/Y = 12

PMT = - $1543.85

Conclusion The monthly payment that the club would pay if they decided to take the loan is : $ 1543.85

The monthly payment that the club would pay if they decided to take the loan is :
