Charlie went out to buy some tools. He spent half of the original amount plus $10 for a drill, half of what was left plus $4 for a sander, then half of what was left plus $2, leaving him with $6.I knew they were going to ask that question. I'll be lying down with a cool cloth on my head if anyone needs me...
How much did he start with?
HERE'S THE ANSWER
(in cleverly done "invisi-type" ... highlight it with your cursor to read ... rereading I discovered a typo so those who did the puzzle before I fixed it will have to add 16 to the final answer ... sorry!)
$100 ($50 + $10= $60, leaving $40; $20 = $4 = $24, leaving $16; $8 + $2 = $10, leaving $6)
