Explanation
## Step 1: Define Variables and Equations### Let
represent the weight of a large box and
represent the weight of a small box. We can set up a system of equations based on the given information:
## Step 2: Solve for
### Subtract the first equation from the second equation to eliminate
:
## Step 3: Solve for
### Substitute the value of
(20) back into the first equation:
## Step 4: Write the Inequality### Let 'L' be the number of large boxes and 'S' be the number of small boxes. The total weight must be less than or equal to 1200 pounds. Since a large box weighs 60 pounds and a small box weighs 20 pounds, the inequality is:
## Step 5: Simplify the Inequality### Divide the inequality by 20:
## Step 6: Rewrite in terms of S### Isolate S:
