Question

Heather opened a lemonade stand on her street. It costs her $5.25 to buy the supplies each day, and she sells lemonade for $1.50 a cup. If she wants to make at least $100.00 in profits (sales - expenses) each day, what is the minimum number of cups of lemonade Heather needs to sell? Input your answer as a whole number.

Answer 1

70 cups

Explanation:

C. P. of lemonade supplies = $5.25

S. P. of one cup of lemonade = $1.50

Let us assume that she should sell n cups of lemonade to make a profit of $100.00.

Therefore, S. P of n cups = $1.50n

Since,

Profit = S. P. - C. P.

Therefore,

100 = 1.5n - 5.25

100 + 5.25 = 1.5n

105.25 = 1.5n

n = 105.25/1.5

n = 70.1666667

n = 70 cups

Answer 2

around 66.66
