Kerri made a small batch of brownies to try out a new recipe before making a much larger batch for a bake sale. She used 2 3 cup of sugar in her first batch, and used 3 3 4 times that amount in her larger batch. Which equation best represents this problem correctly? A) 2 3 x 3 3 4 = 3 6 12 , or 3 1 2 B) 8 12 x 3 9 12 = 3 17 12 , or 4 5 12 C) 2 3 x 15 4 = 30 12 , or 5 2 = 2 1 2 D) 2 3 x 9 4 = 18 12 , or 1 6 12 = 1 1 2
