Kendall is making greeting cards, which she will sell by the box at an arts fair. She paid $40 for a booth at the fair, and the materials for each box of cards cost $5. She will sell the cards
for $10 per box of cards. At some point, she will sell enough cards so that her sales cover her
expenditures. How many cards will that take?

9

Step-by-step explanation:

40 dollars due up front

10 dollars made per sale

5 dollars lost per creation

Realistically speaking she is only making a $5 profit per box she sells;

$5 used up for material cost, $10 made from sales -5+10= 5

To pay the $40 dollar for the booth she would need to make 9 sales with her current profit

40/5 = 9
