David wants to buy 10 lb of hamburger meat for a dinner party. He picks out three packages at the supermarket. Their weights are labeled 2.73 lb, 3.2 lb, and 2.29 lb. How much more meat does David need?

1.78 lb

Step-by-step 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
