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? Let's think first. Chain of thought:
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.
Therefore, the answer is 32.
