Question

Mr. Farnsworth runs a greenhouse, producing tomatoes for his agriculture students. In order to produce delicious tomatoes, there cannot be too much nitrogen (N) in the fertilizer. "Any fertilizer" with over 20 units of nitrogen per weight is considered high-nitrogen." Write an inequality to show the right amount of nitrigen needed.

Answer 1

To represent the condition for the right amount of nitrogen in the fertilizer, we can use the following inequality:

Let \( N \) represent the units of nitrogen per weight in the fertilizer. The condition states that nitrogen levels must not exceed 20 units. Therefore, we can write the inequality as:

\[ N \leq 20 \]

This inequality means that the nitrogen content in the fertilizer must be less than or equal to 20 units to be considered appropriate for producing delicious tomatoes.
