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,
siniylev [52]

Answer:

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: 20\leq 1.50x-6.50.

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

20\leq 1.50x-6.50

20+6.50\leq 1.50x

26.50\leq 1.50x

x\geq \frac{26.50}{1.50}

x\geq \frac{53}{3}

x\geq 17.6666666

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