Question

made a profit of $21.00 selling lemonade. She sold her lemonade for $0.75 per cup, received a tip of $3 from a neighbor, but also had to buy each plastic cup she used for $0.10 per cup. Write an equation to represent this situation

Answer 1

To represent this situation, the equation 'Profit = (0.75 * Number of cups sold + 3) - (0.10 * Number of cups sold)' can be used.

Step-by-step explanation:

To represent this situation, we can use the equation:

Profit = Total Sale - Total Cost

We know that the student sold each cup of lemonade for $0.75 and received a tip of $3, which contributes to the total sale. However, she also had to buy each plastic cup for $0.10, which contributes to the total cost. Therefore, the equation can be written as:

Profit = (0.75 * Number of cups sold + 3) - (0.10 * Number of cups sold)
