Bernie spends $6.50 on ingredients and cups for his lemonade stand. he charges $1.50 for each cup of lemonade. how many cups, x, will bernie need to sell to make a profit of at least $20? inequality that represents this situation: 20≤1.50x−6.50

18 cups.

Step-by-step explanation:

We are given that Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. Inequality that represents this situation: .

To find number of cups x to make a profit of at least  $20 we will use our given inequality.

Therefore, in order to make a profit of at least $20 Bernie need to sell 18 cups of lemonade.
