There are 3 parts to this; part of this has been completed
1. Present value calculation
2. Future value of annuity: ordinary annuity and annuity due
3. Loan interest deductions

1. Present value calculation:
A PVIF  1  (1  0.02)4  ??
B PVIF  1  (1  0.10)2  ??
C PVIF  1  (1  0.05)3  ??
D PVIF  1  (1  0.13)2  ??

2. Future value of an annuity
