Answer: 5 1/4 pounds of bacon and make a total of 7 BLT sandwiches.
To determine the amount of bacon Omar will use and the number of BLT sandwiches he will make, we need to follow these steps:
1. Calculate the amount of bacon used per sandwich:
- It takes 3/4 of a pound of bacon to make 4 sandwiches.
- Divide 3/4 pound by 4 to find the amount of bacon used per sandwich: 3/4 ÷ 4 = 3/16 pound of bacon per sandwich.
2. Calculate the amount of bacon used for 2 full heads of lettuce:
- We know that 5 tomatoes are used for every full head of lettuce.
- Since Omar is using 2 full heads of lettuce, he will need 2 * 5 = 10 tomatoes.
- For every 2 tomatoes used, Omar uses 1 1/20 pounds of bacon.
- Divide the 10 tomatoes by 2 to find the number of times Omar needs to use 2 tomatoes: 10 ÷ 2 = 5.
- Multiply 5 by 1 1/20 to find the amount of bacon used for 2 full heads of lettuce: 5 * 1 1/20 = 5 5/20 = 5 1/4 pounds of bacon.
3. Calculate the number of BLT sandwiches made:
- Divide the total amount of bacon used (5 1/4 pounds) by the amount of bacon used per sandwich (3/16 pound): (5 1/4) ÷ (3/16) = (21/4) ÷ (3/16).
- Invert the divisor and multiply: (21/4) * (16/3) = 21 * 16 / 4 * 3 = 84 / 12 = 7.
- Omar will make a total of 7 BLT sandwiches.
Therefore, Omar will use 5 1/4 pounds of bacon and make a total of 7 BLT sandwiches.
