In years Cedric and Daniel compare their respective balances. To the nearest dollar, what is the positive difference between their balances?
Solution
We may find Cedric's balance by simply finding \12,\!000(1 + 0.05)^{15} \approx \
We may find Daniel balance by finding \12,\!000(1 + 15 \cdot 0.07) \approx \
Therefore, the difference between their balances is roughly \24,\!947.14 - \24,\!600 \approx \boxed{\347}.$
