Problema Solution

Kenny invested $12950 for 8 years and received $1036.00 in interest. At what rate did he invest if the interest was calculated using the simple interest formula?

Answer provided by our tutors

P = $12,950 is the principal


t = 8 years the time


I = $1036.00 is the interest


r = ? the rate


Since I = P*r*t we have:


1036 = 12950*r*8


12950*r*8 = 1036


by solving we find:


r = 0.01 or 10%
