labeled 2.73 lb, 3.2 lb, and 2.29 lb. How much more meat does David need?
1 answer:
Answer:
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

Step-by-step explanation:
Ummmm........ do you still need help?
Let y=total cost
We have 4 friends that paid an extra $6 each and 4 friends that paid regular admission.
Friends that paid extra= 4(x+6)
Friends that paid regular= 4x
Now we need to add those together.
y= 4(x+6) + 4x
Distribute the 4
y= (4*x) + (4*6) +4x
y=4x + 24 +4x
y=8x + 24
