Question

The profit from selling x thousand pocket knives is given by P(x)= 500xln(x)
dollars when x is greater than 0 and less than 2. Find the marginal profit when
1500, ( x = 1.5) pocket knives are sold.

Answer 1

unless im misunderstanding the problem, all you need to do is plug in 1.5 everywhere you see an x. so we have:
\[P(1.5) = 500(1.5)\ln(1.5)\]
