Final answer:
To find Joe's deduction, we need to calculate the total cost of his expenses, which is $220. However, without specific information about Joe's income or tax situation, we can't determine the exact deduction amount.
Step-by-step explanation:
To find Joe's deduction, we first need to calculate the total cost of his expenses. The cab fare is $40, the meal is $150, and the tip is $30. So, the total cost is $40 + $150 + $30 = $220.
Next, we need to calculate the deduction. A deduction is a reduction in taxable income, typically used for expenses related to business or work. In this case, we assume Joe is deducting his expenses related to meeting his client for dinner.
Since we don't have any specific information about Joe's income or tax situation, we can't determine the exact deduction amount. However, if we assume that Joe is deducting the entire $220 as a business expense, then his deduction would be $220.
