Question

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 20MB. write an inequality that shows the number of additional MB (m) that she could add to her email.

Answer 1

9.25 + m ≤ 20

Subtract 9.25 from both sides: m ≤ 20 − 9.25 = 10.75.

So she can add at most 10.75 MB (and m ≥ 0).
