You can put this solution on YOUR website!
+45%2A%28+5%2F2+%2B+15%2F4+%2B+2%2F3+%29+
+225%2F2+%2B+675%2F4+%2B+90%2F3+
+112.5+%2B+168.75+%2B+30+
+311.25+
$311.25 was earned
If you're not allowed to use decimals,
you have to do something like this:
+E+=+225%2F2+%2B+675%2F4+%2B+90%2F3+
+12%2AE+=+12%2A%28+225%2F2+%2B+675%2F4+%2B+90%2F3+%29+
+12%2AE+=+1350+%2B+2025+%2B+360+
+12%2AE+=+3735+
+E+=+3735%2F12+
+E+=+311.25+
OK
