Question 1048913
Question 1048224: a company manufactures and sells bar stools. manufacturing costs consist of a fixed cost of R25 000 per month and a variable cost of R350 per unit. each unit is sold at R600.00. 
determine the linear profit equation



Let x be number of units sold.


Cost, for a month, {{{25000+350x}}}


Revenue, {{{600x}}}


PROFIT, p, is Revenue minus Cost.
{{{highlight(p=600x-(25000+350x))}}}
simplifiable into {{{highlight(highlight(p=250x-25000))}}}.


Be aware, x is being used both for amount of units produced AND for amount of units sold.   The equation only works well when amount sold and amount produced are the same.


Break-even point?  When p=0.
