Answer 1

Given:

When all the students behave well then Ms. Lee reward them by drawing stars on a chart.

The chart has 200 or more starts the class has a party.

Now, the class has 28 stars.

The inequality is,

`28+x\ge200`

Now, solve the inequality,

`\begin{gathered} 28+x\ge200 \\ x\ge200-28 \\ x\ge172 \end{gathered}`

That means the class need 172 or more to be rewarded to earn a party.
