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?

1 answer

To determine the total profit Juan made over the four days of running his lemonade stand, you can use the following expression:

Total Profit = Total Earnings - Total Expenses

Let's break this down based on the information you provided:

  1. Total Earnings: This is the sum of profits made each day.
  2. Total Expenses: This is the sum of the amounts he spent each day.

If we denote:

  • \( E_1, E_2, E_3, E_4 \) as the earnings on each of the four days (with \( E_1 = 12 \) for the first day),
  • \( S_1, S_2, S_3, S_4 \) as the expenses on each of those days,

Then the expression for Juan's total profit over those four days would be:

\[ \text{Total Profit} = (E_1 + E_2 + E_3 + E_4) - (S_1 + S_2 + S_3 + S_4) \]

If the values for \( E_2, E_3, E_4 \) and \( S_1, S_2, S_3, S_4 \) were provided in the table, you would be able to substitute them into the expression to find the total profit.
