 <translate> The second guinea pig eats 2 x 2 = 4 cups of food. The third guinea pig eats 4 + 3 = 7 cups of food. Therefore, Rollo needs a total of 2 + 4 + 7 = 13 cups of food for the guinea pig. So the final answer is 13. <yor> Ẹranko Guinea kejì jẹ 2 x 2 = 4 ife oúnjẹ. Ẹranko kẹta jẹ 4 + 3 = 7 ife oúnjẹ. Nítorí náà, iye tí Rollo nílò fún ẹran ọ̀sìn náà jẹ́ 2 + 4 + 7 = 13 ife oúnjẹ.
