Answer:

1.78 lb

Explanation:

Total meat needed = 10 lb

David picks out 3 packages at the supermarket.

Each package weighs

2.73 lb

3.2 lb

2.29 lb

Total weight of the 3 packages = 2.73 lb + 3.2 lb + 2.29 lb

= 8.22 lb

How much more meat does David need?

Amount of meat David needs more = Total meat needed - Total weight of meat picked at the supermarket

= 10 lb - 8.22 lb

= 1.78 lb

David needs 1.78 lb more of meat to complete the total 10 lb meat needed
