Question 1188721
.
if you deposit Php 8000 into an account paying 7% annual interest compounded quarterly, 
how long until is Php 12400 in your account ?
~~~~~~~~~~~~~~~~~~~~~



It will take 26 quarters, precisely and exactly, which is 6 years and half.


You can not accept 25.26 quarters from the solution by @Theo.


You must round it to the closest greater quarter, which is 26 quarters, in order for

the bank was in position to make the last compounding.


26 quarters is your correct answer.


25.26 quarters is not enough.
