204.8 apples.
First you would find out how many ounces are in 8 pounds, which would be 128. then do 128/5 to get 25.6 < that would be how many apples are in 8 pounds. Next you would do 224/28 to find out how many of the 8 pounds you can buy for 224 dollars. so you get 8 from that. So now we do 25.6*8 to get 204.8 apples.
