Ashley opened a lemonade stand on her street it costs her $12.50 cents o buy the supplies each day and she sells lemonade for $2.50 a cup. If she wants to make at least $200 in profits a day she hat is the number of cups she has to sell
To calculate the number of cups Ashley has to sell in order to make at least $200 in profits, we need to consider the cost of supplies and the selling price of each cup of lemonade.
Let x be the number of cups she needs to sell.
Total cost = $12.50
Total revenue = $2.50 * x
To make at least $200 in profit:
Total revenue - Total cost ≥ $200
$2.50x - $12.50 ≥ $200
$2.50x ≥ $212.50
x ≥ $212.50 / $2.50
x ≥ 85
Therefore, Ashley needs to sell at least 85 cups of lemonade to make at least $200 in profits.
