Question

3. A young girl is opening a lemonade stand in front of her house. It cost her $12 to buy

lemonade mix. She buys a pack of 500 cups for $9. She also buys a pitcher for $4. Each pitcher
holds 8 cups of lemonade. She sells 107 cups of lemonade that day. She charges 50 cents a
cup for the lemonade.

Answer 1

Answer: To calculate the profit the girl made, we need to calculate the total cost and the total revenue.

The cost of the lemonade mix, cups, and the pitcher is:

$12 + $9 + $4 = $25

The number of pitchers needed to serve 107 cups of lemonade is:

107 cups ÷ 8 cups per pitcher = 13.375 pitchers (round up to 14 pitchers)

The cost per cup of lemonade is:

Total cost / Total cups = $25 / 500 cups = $0.05 per cup

The revenue from selling 107 cups of lemonade at $0.50 per cup is:

107 cups x $0.50 per cup = $53.50

The profit is the revenue minus the cost:

Profit = $53.50 - $25 = $28.50

Therefore, the girl made a profit of $28.50 from her lemonade stand that day.
