Question

make this shorter and sound like a 7 year old To figure out which prize is better we can make a list for each one where Choice A starts with just ten cents but doubles every single day and Choice B starts with five dollars and just adds five more dollars every time so on the first day you have $0.10 for A and $5.00 for B and then on day two it is $0.20 for A and $10.00 for B and by day three it is $0.40 for A and $15.00 for B and on day four it is $0.80 for A and $20.00 for B and on day five it is $1.60 for A and $25.00 for B and on day six it is $3.20 for A and $30.00 for B and on day seven it is $6.40 for A and $35.00 for B and on day eight it is $12.80 for A and $40.00 for B and on day nine it is $25.60 for A and $45.00 for B and finally on day ten you get $51.20 for A while B only gives you $50.00 so Day 10 is when Choice A finally wins because doubling makes numbers grow super fast like a magic beanstalk once they get going.

Answer 1

Choice A: starts with 10¢ and doubles.
Choice B: starts with $5 and adds $5.
Day 1: 10¢ vs $5. Day 2: 20¢ vs $10. Day 5: $1.60 vs $25. Day 10: $51.20 vs $50.00.
A wins on day 10 — doubling is like a magic beanstalk that grows huge! I pick A.
