Lauren opened a lemonade stand on her street. It costed her $8.00 to buy the supplies each say and she sells lemonade for $2.50 a cup if she wants to make at least $175.00 in profits (sales-expenses) each day what is the minimum number of cups of lemonade Lauren needs to seell
To make at least $175.00 in profits each day, Lauren needs to earn $175 + $8 (expenses) = $183.00 in total sales.
If Lauren sells each cup of lemonade for $2.50, she needs to sell $183.00 / $2.50 = 73.2 cups of lemonade.
Since Lauren cannot sell a fraction of a cup, she needs to sell at least 74 cups of lemonade to make a profit of at least $175.00 each day.
