the profit (p), in dollars, for a company is modeled by the function p(x) = -750x^2 + 15,000x, where x is the number of items produced. For which values of x will the company lose money?

• math -

For the company to lose money, p(x)<0
We have: p(x)=x(15000-750x)
And since x is the number of items produced ==> x>0
Thus, 15000-750x<0;
750x>15000;
x>20

Therefore, the company loses money for x>20 items
