Question 1181425
--------------------------------------------------------------
(a) What is the slope of the equation P = 140x - 2000?
-------------------------------------------------------------


{{{highlight(140)}}}{{{dollars/microcomputer}}}


-----------------------------------------------------------------------------
(b) How many microcomputers must be sold each day for the company to make a profit?
-------------------------------------------------------------------------


If at least $1 of profit is "profit", then  {{{140x-2000=1}}}
{{{140x=2001}}}
{{{x=14.293}}}
but need a whole value for x.
14 computers is not enough for "profit".
ANSWER:  <b>15 computers</b>.
------
Or the $1 part is not necessary.
{{{140x=2000}}}
{{{x=200/14=100/7}}}
{{{x=14.286}}}-------------Break-Even value, not a whole value result, so need <b>15</b> microcmputers.


The amount of profit would be $100.
