Hannah is sending some song files to a friend. She has already attached 9.25 MB of music to her email. The email program she is using will not send a message above 20 MB. What is the solution of an inequality showing the number of additional MB (m) that she can still attach to her email?

Answer 1

The inequality to represent Hannah's situation is:

9.25 + m ≤ 20

Where "m" represents the additional MB she can still attach to her email.

We add 9.25 to both sides to isolate "m":

m ≤ 20 - 9.25

Simplify:

m ≤ 10.75

Therefore, the solution is:

m ≤ 10.75 MB
