Kim wants to have a lemonade stand at the community fair. It cost him two dollars to make each cup of lemonade plus a $40 renters fee for the stand. He sells the lemonade for six dollars per cup. How many cups does a lion have to sell to break even

Kim needs to sell a total of $40 (rental fee) + $2 (cost per cup) = $42 worth of lemonade to break even.

So, he needs to sell $42 / $6 (selling price per cup) = 7 cups of lemonade to break even.
