We have to use the simple interest formula


I=P* r* t

Where P = 13,000, r = 5% (0.05), t = 90 (0.25 years). Let's replace these values to find the interest


I=13,000*0.05*0.25=162.50

(a) The amount of interest is $162.50.

(b) The total amount that must be paid after 90 days is $13,162.50.

Because we have to add the total interest with the amount borrowed.
