Answer:
Omar should weigh 9 pounds and 7 ounces
Step-by-step explanation
Each pound is equal to 16 ounces. So with 5 ounces each week for 4 weeks in all, you get a total of 20 ounces. Add the first 3 to get 23 before taking away 16 ounces to add another pound to the 8. This leaves you with 7 ounces. SO Omar should weigh 9 pounds and 7 ounces after 4 weeks.
