Question 1153393
.
<pre>

The growing coefficient (growing factor) in this case is, by the definition


    r = {{{e^0.10}}} = {{{2.71828^0.10}}} = 1.105171,


where  e = 2.71828 is the base of natural logarithms (the Euler's number).


Thus the equivalent effective rate of interest compounded annually is 10.5%, approximately.

Yesterday I solved a TWIN problem under this link

This time, I simply copied that solution and changed numbers in it . . . 



As I see, you love posting TWIN problems very much . . . (instead of studying on how to solve problems on your own from my samples and templates).
