Answer:

C.

Step-by-step explanation:

If Erin has 9 more shells than Jamie, then 27 minus 9 would be equivalent to the amount of shells Jamie has.

This can be represented by:

[tex]27-9=j[/tex]

Which can be rewritten as:

[tex]27=j+9[/tex]

by adding 9 to both sides.

To solve, subtract 9 from 27.

[tex]27-9=18[/tex]

Jamie has collected 18 shells.
