1.Find the interest rate on a loan charging $810 simple interest on a principal of $3750 after 6 years.
2.Find the term of the compound interest loan. (Round your answer to two decimal places.)
4.9% compounded quarterly to obtain $8600 from a principal of $2000.
1)Interest per year 810/6= 135
Simple interest = Amount * Rate*Time
135 = 3750 *r * 1
135 = 3750*r
r = 135/3750
= .036 or 3.6%
2) Quarterly rate = 4.9/4 = 1.225% [4 quarters in a year]
Term (number of quarters) = IN[Future value/present value]/IN(1+r)
= IN[8600/2000]/IN[1+.01225]
= IN 4.3/ IN 1.01225
= 1.45862/ .012176
= 119.79468
Number of years =119.79468 / 4
= 29.95 years
Term : 29.95
