Answer:
The present value decreases
Step-by-step explanation:
The present value of an amount of $100 to be received in one year, at an interest rate 'r', is:

As we can see, since the interest rate is in the denominator of the expression, if 'r' increases, then the present value decreases.
I.e. If the interest rate were zero, then $100 would buy the same amount of goods today as it would in one year, however, if the interest rate is positive, $100 today would buy more goods than it would in one year.
