Juan ran the lemonade stand for 3 more days after his first day profit of $12. Each day, he used the money from sales to purchase more lemons, cups, and sugar to make more lemonade. The table shows how much he spent and earned each day.What is the expression needed to find his total profit? What was his total profit? Skip to navigation

To find Juan's total profit over the 4 days, we first need to establish the expression for his total profit. Profit is generally calculated as the total earnings minus total expenses.

Assume the following for each day:

  • Let \( E_i \) represent the earnings (revenue) on day \( i \).
  • Let \( C_i \) represent the costs (expenses) on day \( i \).

The total profit \( P \) can be expressed as:

\[ P = (E_1 + E_2 + E_3 + E_4) - (C_1 + C_2 + C_3 + C_4) \]

Where:

  • \( E_1 \) = earnings on the first day
  • \( E_2 \) = earnings on the second day
  • \( E_3 \) = earnings on the third day
  • \( E_4 \) = earnings on the fourth day
  • \( C_1 \) = expenses on the first day
  • \( C_2 \) = expenses on the second day
  • \( C_3 \) = expenses on the third day
  • \( C_4 \) = expenses on the fourth day

To determine the total profit, you would calculate the sum of his earnings over the 4 days and subtract the sum of his expenses over the same period.

If you could provide the specific values from the table regarding his earnings and expenses for each day, I can help you calculate the exact total profit Juan made.
