[Question]For the gala luncheon planning committee, Margaret wants to serve chicken salad sandwiches using mini croissants. She wants there to be enough food that each person on the committee can have 2 sandwiches each. Her bakery offers 12 minis croissants for $8.00. There are 24 people on the committee. How much will she spend on croissants?
[Answer]There are 24 people on the committee and she wants 2 sandwiches per person so that's 24 * 2 = 48 sandwiches. She can buy the croissants by the dozen and she needs 48 croissants so she needs 48 / 12 = 4 dozen croissants. A dozen croissants cost $8.00 and she needs 4 dozens so that will costs 8 * 4 = $32.00. The answer is 32.

[Question]A truck driver’s heavy semi truck can go 3 miles per gallon of gas. The truck driver needs to put gas in his truck at one gas station, but wants to put the minimum amount he needs to get him to a much cheaper gas station 90 miles away. He already has 12 gallons of gas in his tank. How many more gallons does the truck driver need to put in his semi to make it to the cheaper gas station?
[Answer]The truck driver can go 3 * 12 = 36 miles on the gas in his tank. He needs to go 90 - 36 = 54 more miles. Thus, the truck driver needs to put 54 / 3 = 18 more gallons of gas in his semi. The answer is 18.

[Question]Two months ago, Wilson had a total of $150 in his bank account. Then last month, he deposited $17. A few days after, he made a withdrawal. This month, he deposited $21 so he has $16 more than what is in his account two months ago. How much did Wilson withdraw last month?
[Answer]Wilson had $150 + $17 = $167 two months ago before making a withdrawal. His money in his account now is $150 + $16 = $166. Since he deposited $21 this month, this means there was $166 - $21 = $145 last month after making a withdrawal. Therefore, Wilson withdrew $167 - $145 = $22. The answer is 22.
