Homework Help: 6th Grade Math

Posted by Brandi on Monday, March 30, 2009 at 3:45pm.

Carmen recieved some money for her birthday on Friday. That night, she took her friend out to dinner. She spent half of her check for dinner. Then she tipped the waiter $6. The next evening she went to dinner alone, she spent half of the money she had left, and she tipped the waiter $2. The nest night, she went to dinner again, spent half of the money she had left, and tipped the waiter $1. At this time she had $6 left. How much money did she originally have?
(Please show work, if possible.) THANK YOU!

work this question backwards

Start with the 6 dollars she had left and add up.
6 + 1 =7
7 x 2= 14
and so on...

Wait a second....
14+2=16
16x2=32
32+6= 38
38x2 =
I think you may have forgotten the 6 dollar tip

Sorry 64 isn't quite right in my second calculation
