Karen has 32 quarters in her piggy bank.  Her older brother Christopher has 64 quarters in his piggy bank.  How much more money does Christopher have?
Christopher has 64 quarters so he has 64*.25 = $<<64*.25=16.00>>16.00
Karen has 32 quarters so she has 32*.25 = $<<32*.25=8.00>>8.00
If Christopher has $16.00 and Karen has $8.00 then Christopher has 16-8 = $<<16-8=8.00>>8.00 more than Karen
