The profit of a PC manufacture company of making x personal computers (PC) per day is given by the following formula:
$f(x)=-0.01x^2+12x+240$

How can we find the profit in dollars in the following cases:
for 20 PCs, 50PCs and 200PCs

Thanks

The profit of the company when are produced 20 PCs is given

$f(20)= -0.01(20)^2+12(20)+240=-4+240+240=476$

The profit of the company when are produced 50 PCs is given

$f(50)= -0.01(50)^2+12(50)+240=-25+600+240=815$

The profit of the company when are produced 200 PCs is given

$f(200)= -0.01(200)^2+12(200)+240=-400+2400+240=2240$

Hope these help!!
