To find Juan's total profit over the 4 days he ran the lemonade stand, we need to set up an expression based on his earnings and expenses for each day.
Let's denote:
- \( E \) as the total earnings over the 4 days.
- \( S \) as the total expenses over the 4 days.
- The total profit can be calculated using the formula:
\[ \text{Total Profit} = \text{Total Earnings} - \text{Total Expenses} \]
From the information provided, we know that he made a profit of $12 on his first day and ran the stand for 3 additional days.
The total profit for the 4 days can be calculated as follows:
- First Day: Profit = $12
- Subsequent Days: We need to know the profit or loss on those days based on the table of expenses and earnings (which you mentioned but did not provide).
Assuming the information from the table includes daily earnings and expenses, you would list the earnings and expenses for all 4 days:
For example:
- Day 1: Profit = Earnings - Expenses = $12 (already given)
- Day 2: Profit = Earnings - Expenses
- Day 3: Profit = Earnings - Expenses
- Day 4: Profit = Earnings - Expenses
You would then add those profits together:
\[ \text{Total Profit} = 12 + \text{(Day 2 Profit)} + \text{(Day 3 Profit)} + \text{(Day 4 Profit)} \]
To find the total profit, substitute the earnings and expenses for the remaining days into the expression above.
If you provide the detailed earnings and expenses from the table for each day, I can help calculate the exact total profit.
