If my math is correct this should be a simple equation. First you’d start off by figuring out how much money chicken costs per one pound. 53.28 / 4.5 = $11.84 per pound Now take how much money the chicken costs per pound and divide it by how much Benjamin spent. 59.20 / 11.84 = 5 pounds Your answer should be exactly 5 pounds I apologize if this is incorrect math, but the equation seems simple at first glance.
