To find his total profit, we need to add up all of Juan's earnings from sales and then subtract all of his expenses. Given that he earned $12 on his first day, we can express the total profit as follows:
Total Profit = (Total Earnings) - (Total Expenses).
From the options provided, the first option seems to describe this process of summing the earnings and subtracting the expenses.
- If we assume:
- Earnings: 16 (first day profit), 22 (second day profit), 18 (third day profit)
- Expenses: 7 (cost first day), 12 (cost second day), 9 (cost third day)
Then the expression for total profit based on the information provided would be: (16 + 22 + 18) - (7 + 12 + 9)
From the options given, the expression that matches this activity is: (16 + 22 + 18 + 7 - 12 - 9)
Now for the total profit calculation with specific values:
Assuming the total earnings for the four days (first day + 3 subsequent earning days) would be: 16 + 22 + 18 = 56
Total expenses across the days would be: 7 + 12 + 9 = 28
Now we can calculate: Total Profit = Total Earnings - Total Expenses = 56 - 28 = 28
So, the total profit Juan made is $28.
The correct answers based on the options given would be:
- The expression needed to find his total profit is (16 + 22 + 18 + 7 - 12 - 9).
- His total profit is $28.
