Alex makes ceramic bowls to sell at a monthly craft fair in a nearby city. Every month, she spends $50 on materials for the bowls from a local art store. At the fair, she sells each completed bowl for a total of $25 including tax. Which equation expresses Alex's profit as a function of the number of bowls that she sells in one month.

1) p(x) = 50x+25
2) p(x) = 15x+25
3) p(x) = 25x
4) p(x) = 25x-50

Why?



Answer :

the answer is      p(x) =  25x - 50
profit = total selling price- cost
x = number of bowls he must sell to make a profit
if he sell 1 bowl he will make a lost
                2 bowls even up
thus he must sells 3 bowls or more to make a profit
