Carla adds a can of chilis, two cans of beans, and 50% more tomatoes than beans to a normal batch of chili. If she makes a quadruple batch, how many cans of food does she need? Let's think first. Chain of thought:
First find the number of cans of tomatoes in a normal batch of chili: 2 cans * 150% = 3 cans. Then add the number of cans of each type of food to find the total number of cans per batch: 3 cans + 2 cans + 1 can = 6 cans. Then multiply the number of cans per batch by the number of batches to find the total number of cans: 6 cans / batch * 4 batches = 24 cans.
Therefore, the answer is 24.
