It costs you $13.50 to open your lemonade stand. After selling lemonade for 2 hours you make $13.50 in sales. How much money do you have since starting your lemonade stand?

$0

Step-by-step explanation:

"Costs" means negative. So, if it costs $13.50 to open a lemonade stand, then it would be represented by -13.50"In two hours, you make $13.50. Those $13.50 are a gain. So, it would be positive. Therefore, it would be represented by 13.50.Write your expression: -13.50 + 13.50-13.50 + 13.50 = 0So, you have $0 since starting your lemonade stand.

I hope this helps!
