Answer: 720
Step-by-step explanation: to solve this problem, we do 15*8*12= 1440
this shape is half of that though, so we do 1440/2= 720, so the answer is 720
The loan's effective rate and interest compound every two months then the value of n would be 6.
Given that,
When calculating a loan's effective rate, the interest compounds every two months.
We have to determine,
What value of n do you plug into your equation?
According to the question,
The calculation of compounded interest would be derived with the following formula:

In a year there are 12 months and when the interest rate is said to be compounded every two months then it implies that the number of months would be 6 months.
Then,
The value of n is,

Hence, The loan's effective rate and interest compounds every two months then the value of n would be 6.
