The present value of $1 payable in the future decreases: a. The higher is r and the sooner it is to be paid.

b. The higher is r and the longer the time until it is paid.

c. The lower is r and the sooner it is to be paid.

d. The lower is r and the longer the time until it is paid.

Can I understand this using formula which is signma n to t=1 ct/(1+R)^t? As theinterest and number of periodsincrease, FVincreaseorPVdecreases. Is this right?

Please help me

Thank you!
