You can put this solution on YOUR website!
Let +x+ = the toal amount spent
+.25x+ = amount spent on food items
+.3x+ = amount spent on crockery
+130+ = amount spent on bicycle
--------------------------------------
+.25x+%2B+.3x+%2B+130+=+x+
+x+-+.55x+=+130+
+.45x+=+130+
+x+=+288.89+
---------------------
+.3%2A288.89+=+86.67+
She spent $86.67 on crockery
------------------------------
check:
+.25%2A288.89+=+72.22+
+72.22+%2B+86.67+%2B+130+=+288.89+
OK
