We want to find out how much it costs for each pound of feed
For chicken feed 12 divided by 8.40
$1.43 for 1 pound of chicken feed
For goat feed 75 divided by 60
$1.25 for 1 pound of goat feed
For dog feed 50 divided by 37.50
$1.33 for 1 pound of dog feed
For pig feed 80 divided by 62.80
$1.27 for 1 pound of pig feed
When reviewing all the answers per pound for feed, chicken feed is the most expensive per pound.
Hope this helps:)
