To calculate how many BLT sandwiches Omar will make and how much bacon he will need when using 2 full heads of lettuce, let's break it down step by step:
-
Determine the number of tomatoes needed:
Since Omar uses 5 tomatoes for every full head of lettuce, for 2 full heads of lettuce, he will need: \[ \text{Tomatoes} = 5 \text{ tomatoes/head} \times 2 \text{ heads} = 10 \text{ tomatoes} \]
-
Calculate the amount of bacon needed:
Omar uses \( \frac{1}{2} \) pound of bacon for every 2 tomatoes. Therefore, for 10 tomatoes: \[ \text{Pounds of bacon} = \frac{1}{2} \text{ pound} \times \left( \frac{10 \text{ tomatoes}}{2 \text{ tomatoes}} \right) = \frac{1}{2} \times 5 = \frac{5}{2} \text{ pounds} = 2.5 \text{ pounds} \]
-
Determine the number of sandwiches made:
It takes 1 pound of bacon to make 4 BLT sandwiches. Since Omar will use 2.5 pounds of bacon, the number of BLT sandwiches he can make is: \[ \text{Sandwiches} = 4 \text{ sandwiches/pound} \times 2.5 \text{ pounds} = 10 \text{ sandwiches} \]
In summary, if Omar is making enough BLT sandwiches to use 2 full heads of lettuce, then he is going to use 2.5 pounds of bacon and will make a total of 10 BLT sandwiches.
