Answer:
$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 = 0
- So, you have $0 since starting your lemonade stand.
I hope this helps!
