To determine how much meat the caterer should order for 100 guests, we can use the concept of proportionality.
From the information provided:
- 25 guests require 40 pounds of meat.
We can calculate the amount of meat needed per guest:
\[ \text{Meat per guest} = \frac{40 \text{ pounds}}{25 \text{ guests}} = 1.6 \text{ pounds per guest} \]
Now, to find out how much meat is needed for 100 guests, we can multiply the amount of meat per guest by the number of guests:
\[ \text{Meat for 100 guests} = 1.6 \text{ pounds per guest} \times 100 \text{ guests} = 160 \text{ pounds} \]
So, the caterer should order 160 pounds of meat for 100 guests. The correct response is:
160 pounds.
