Question 252473
We have the formula

(i) {{{I = PRT}}}
putting given information in, we get
(ii) {{{I = 52486(.1276)(t)}}}

July 8 to July 8 = 366 days
July 8 to October 15 = 99 days
So, time = 1 + 100/365 = (365+100)/365 ~ 1.2739726 yrs.
From (ii), we get
(iii) {{{I = 52486*.1276*1.2739726}}}
{{{ I = 8532.07}}}
