o Compound interest? of applied values, in this modality the value of the rate of interest is levied on the upstream of the last period, so the so-called interest rates occurs. The formula used in these cases is as follows:
m = c. [Tex] (1+i)^{n} [/text]
as presented by the question of the question, there is a one Compound interest situation, where Julia knows that the rate of interest of the operation is 1.5% per month . She wants to know what is the equivalent rate for a year, so you have to:
[text] (1+i)^{n} [/text] < /P>
[Tex] (1+0.015)^{12} [/Tex]
[Tex] (1.015)^{12} [/Tex]
1.1956
1.1956- 1
0.1956
0.1956 x 100 = 19.56% < /P>
Thus, it can be stated that the interest rate value corresponding to 1.5% per month for the period of 1 Year is from 19.56%
