Question

The equation $p=\frac{2n}{3}-10$ shows the profit, $p$, from selling $n$ cups of lemonade. Which of the following best describes the relationship between $p$ and $n$?

• A. As $n$ increases , $p$ decreases
• B. As $n$ increases, $p$ increases
• C. As $n$ increases, $p$ remains the same
• D. As $n$ increases, $p$ sometimes increases and some times decreases

Answer 1

The correct option is B As $n$ increases, $p$ increases

In the question, $p$ show profit and $n$ show selling. If $n$ increase then $p$ is also increase and if $n$ decrease $p$ is also decrease.

Hence option B is answer.
