The given function is
.... (1)
where, f(x) is the total revenue at price x.
We need to find the price x at which the weekly revenue is maximum.
The leading coefficient of the given function is -300, which is a negative number. So, it is a downward parabola and vertex of a downward parabola is the the point of maxima.
If a parabola is defined as
... (2)
then the vertex of the function is

It will receive 300,000 dollars when:
250,000 is return of capital and 50,000 will be considered profit.
Explanation:
1,000 x 300 months = 300,000 dollars
The IRR will make the payment match the present value of the $250,000 principal
That will be the yield of the investment.
C 1,000.00
time 300
rate 0.001251129 ( we solve for the rate using excel goal seek or a financial calcualtor
PV $250,000.0000
Now, as this are monthly payment we multiply by 12 to get the annual convertible rate:
