Problema Solution

The principal P is borrowed and the loans future value A at time t is given.Determine the loans simple interest rate r to the nearest tenth of a percent. P= $3800.00, A= 3885.50, T= 6 months

Answer provided by our tutors

simple interest   I = PRT/100

Interest  = A - P = 3885.50 - 3800 = 85.50

R = I/PT = 85.50*100/3800*(6/12)

R = 8550*12/3800*6

R = 4.5%
