My question is: 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? Your thoughts:
Christopher has 64 quarters so he has 64 * .25 = $16.00. Karen has 32 quarters so she has 32 * .25 = $8.00. If Christopher has $16.00 and Karen has $8.00 then Christopher has 16 - 8 = $8.00 more than Karen. The final answer: 8.
