Four people in a law firm are planning a party. Mary will buy a platter of pasta for $20 and a loaf of bread for $2. Elle and Andrea will split the cost for buying 4 cans of soda which cost $1.50 each, and chicken wings for $10. Joe will buy a cake that costs $5. How much more will Mary spend than the rest of the firm put together? Let's think first. Chain of thought:
Mary will spend $20 + $2 = $22. Elle and Andrea will spend $1.5 x 4 = $6 for the soda. Elle and Andrea will spend $6 + $10 = $16 for the soda and chicken wings. Elle, Andrea, and Joe together will spend $16 + $5 = $21. So, Mary will spend $22 - $21 = $1 more than all of them combined.
Therefore, the answer is 1.
