To determine how many pounds of burger meat you need for 175 burgers, with each burger weighing 3 pounds, you can use the following calculation:
\[ \text{Total weight of burger meat} = \text{Number of burgers} \times \text{Weight per burger} \]
Substituting the values:
\[ \text{Total weight of burger meat} = 175 , \text{burgers} \times 3 , \text{lbs/burger} = 525 , \text{lbs} \]
You will need 525 pounds of burger meat to make 175 burgers that weigh 3 pounds each.
