#### Work Step by Step

We are given the function $P(x)=45x-100000$, which models the relationship between the number of computer briefcases x that a company sells and the profit the company makes, $P(x)$. To find $P(4000)$, we can plug 4000 into the given function. $P(4000)=45(4000)-100000=180000-100000=80000$
