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