Let's say Rhonda has m marbles.

The total number of marbles that Ammon has is m+<<+55=55>>55

Amon & Rhonda combined have m+(m+55) = 215

This means the total number of marbles they have together is 2m+55 = 215

2m=215-55

The total number of marbles that Rhonda has is m=160/2

Rhonda has m=80 marbles.
