Jason bought pecans in bulk at the grocery store. He paid $19.20 for 2 1/2pounds of pecans. How much did Jason pay per ounce? (1 pound = 16 ounces)

Answer 1

First, convert 2 1/2 pounds to ounces: 2 1/2 pounds * 16 ounces/pound = <<2.5*16=40>>40 ounces
Then divide the total cost by the number of ounces to find the price per ounce: $19.20 / 40 ounces = $<<19.20/40=0.48>>0.48/ounce. Answer: \boxed{0.48}.
