Question 915482: William and his family eat at a fancy restaurant that automatically charges 18% gratuity tip. If his bill total is $53.02, how much was the bill before gratuity was included?
I tried $53.02 x .18 = $9.54
$53.02 - $9.54 = $44.48. However, my friend is telling me that the answer should be $44.93. I don't know how he got to that.
Can you show me how you solved it, please? Thank you.

Let +x+ = bill before gratuity
+x+%2B+.18x+=+53.02+
+1.18x+=+53.02+
+x+=+44.93+
