Charlie the Chocolate Freak

Posted August 26 - Sept 1, 1996

Charlie would get 15 x 7 = 105 chocolate bars with the first option.With the second option, Charlie would get 1 chocolate bar the first day.

2 chocolate bars the second day.

4 chocolate bars the third day.

8 chocolate bars the fourth day.

16 chocolate bars the fifth day.

32 chocolate bars the sixth day.

64 chocolate bars the seventh day.

Altogether, Charlie would get 1 + 2 + 4 + 8 + 16 + 32 + 64 = 127 chocolate bars with this choice.The first option might be better for Charlie's teeth, but the second will better satisfy his appetite.

Boogle [judyfeng@mhv.net] gave Minus the right answer and some insight into Charlie's habit:

The answer is...option number two. It gives him a total of 127 chocolate bars a week, however slowly, but the fast way, option numero uno, gives only 105 chocolate bars. Being the chocolate freak he is, Charlie will settle for the 22 extra bars.Christian T. Tawfik [a9504526@unet.univie.ac.at] of Austria also submitted a correct solution:

In my opinion he should choose the second one. By getting 15 bars every day heŽs got 105 at the end of the week. With the other possibility heŽll get 1+2+4+8+16+32+64=127 bars at the end of the week.Minus wanted us to mention Bob Hansen [hansen@west.ora.com] and Michael, Sr. Joseph Muratore [cqweave@ix.netcom.com] for sending in their answers of Option #2.
