Rob wanted an allowance. His father gave him a choice of getting it on a weekly or daily basis. He said he would either pay him $1.25 a week or pay him in the following manner for a week: On Monday he would give him $0.01; On Tuesday $0.02; On Wednesday $0.04 and on through Sunday.

Take the daily...He'll get 2 cents more per week.
1+2+4+8+16+32+64 = 127

Monday-Tuesday-Wednesday-Thursday-Friday-Saturday-Sunday
.01 + .02 + .04 + .08 + .16 + .32 + .64
= 1.27
So, his options are $1.27 in loose change over a long period of time or $1.25 all at once. Take the $1.25. Taking the $1.27, you'd lose more than the 2-cent difference since most of it will be in pennies and nickels which have a tendency to disappear.

take the start with 1 penny since it would result in .01 + .02 + .04 + .08 +.16 + .32 + .64 = $1.27/week

.01+.02+.04+.16+.32+.64+1.28
by sunday he already gets more than the 1.25/week so the 2nd way...
