Jason bought pecans in bulk at the grocery store. He paid $19.20 for
2
1
2
pounds of pecans.
How much did Jason pay per ounce? (1 pound = 16 ounces)
First, find how many ounces are in 2 1/2 pounds: 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 cost per ounce: $19.20 / 40 ounces = $<<19.20/40=.48>>.48/ounce. Answer: \boxed{.48}.
