The algebraic expression in Example 1 has separate variables x and y in different terms. But in Example 2, the term 50lw contains two variables multiplied together. Example 2 also represents cost using area and fencing calculations.
The algebraic expression in Example 1 is 4x + 5y + 3, where the variables x and y appear separately in different terms. In Example 2, the expression is 200l + 160w + 50lw. The important difference is that the term 50lw contains two variables multiplied together. Example 1 includes a constant term 3, but Example 2 has no constant term. Also, Example 1 is about counting pens and pencils, while Example 2 is related to the cost of fencing and seeds.
