Final answer:
To find Samuel's Coffee Shop profit, deduct the expenses ($3,900) from the income ($5,500), resulting in a profit of $1,600 for the week.
Step-by-step explanation:
To calculate Samuel's Coffee Shop profit for the week, you subtract the total expenses from the total income. In this case, the income is $5,500 and the expenses are $3,900. Using the formula for profit:
Profit = Total Income - Total Expenses
Profit = $5,500 - $3,900 = $1,600
Therefore, Samuel's Coffee Shop had a profit of $1,600 for the week.
