If Hillary has thirteen fewer pencils than Mark, what algebraic expression could represent how many Hillary has? Use "m" to represent the number of pencils that Mark has.

m-13

Step-by-step explanation:

Number of pencils that mark has = m pencils

We have to find the number of pencils that Hillary has and we have to represent it in form algebraic expression

As per given information,

Hillary has 13 fewer pencils than has Mark,

So, number of pencils that Hillary has = m - 13

Algebraic form of Hillary Pencils = m-13

Hence, the correct answer is m-13
