First find the number of cans of tomatoes in a normal batch of chili: 2 cans * 150% = <<2*150*.01=3>>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 = <<3+2+1=6>>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 = <<6*4=24>>24 cans
