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.

Question

What is the expression needed to find his total profit?
16 + 22 + 18 + 7 - 12 - 9

What was his total profit?

Answer 1

To find Juan's total profit over the 4 days, starting with his first day profit of $12 and considering his expenses and earnings each subsequent day, we can break the expression down accordingly:

The expression provided is: \[ 16 + 22 + 18 + 7 - 12 - 9 \]

Here, the first four numbers (16, 22, 18, and 7) represent Juan's earnings on each of the 3 additional days plus his first day profit (which seems to have been excluded from the sales). The last two numbers (12 and 9) represent his expenses on those days.

To compute the total profit, we can calculate it step by step:

1. Calculate total earnings: \[ 16 + 22 + 18 + 7 = 63 \]

2. Calculate total expenses: \[ 12 + 9 = 21 \]

3. Now, find the total profit: \[ \text{Total Profit} = \text{Total Earnings} - \text{Total Expenses} = 63 - 21 = 42 \]

So, Juan's total profit after 4 days, including his first day's profit, is $42.
