Briella opened a lemonade stand on her street. It cost her $11 to buy the supplies each day and she sells lemonade for two dollars a cup. If she wants to make at least $75 in profit sales and expenses each day what is the minimum number of cups of lemonade Brie needs cell
Briella's profit is calculated by subtracting the cost of supplies from the total revenue she makes from selling lemonade. Let the number of cups Briella needs to sell be x.
Total revenue = 2x (selling price per cup)
Total cost = 11 (cost to buy supplies)
Briella wants to make at least $75 in profit:
Total revenue - Total cost ≥ $75
2x - 11 ≥ 75
2x ≥ 86
x ≥ 43
Therefore, Briella needs to sell a minimum of 43 cups of lemonade in order to make at least $75 in profit.
