A teacher had m markers for her class to use. During a sale, she bought 18 more markers. Write an expression that shows how many markers the teacher has now.

Answer 1

To represent the total number of markers the teacher has now, you can start with the number of markers she originally had, which is \( m \), and then add the 18 markers she bought during the sale.

The expression that shows how many markers the teacher has now is:

\[ m + 18 \]
