You can put this solution on YOUR website!
Let +x+ = the number of shells that Andrew collects
Elliot collects +1.2x+ shells
Ryan collects +1.4x+ shells
------------------------------
If I say:
+1.4x+=+%28+1+%2B+k+%29%2Ax+
+k+ tells me the decimal that left side
exceeds the right side by
+1+%2B+k+=+1.4+
+k+=+.4+
+.4%2A100+=+40+
Ryan collected 40% more shells than Andrew
