Q: Consider the following profit functions:
P(x) = 5000 - (1000/(x-1)) , x > 1
P(x) = 5000 - (1000/(x-2)) , x > 2
where P(x) indicates the annual profit in thousands of dollars, and x is the number of items sold in thousands.
Find out the number of items sold, in each case, to achieve the annual profit value of 4000.
