In this case, we'll have to carry out several steps to find the solution.
Step 01
Data
M = $8000
r = 11%
t = 3 months
C = ?
Step 02:
I = C * (r /1200) * t
M = I + C
M = C ( 1 + r/1200 * t)
8000 = C (1 + 11/1200 * 3)
8000 = C (1.0275)
8000 / 1.0275 = C
7785.888 = C
The answer is:
The amount borrowed by Jay was $7785.89 .
