Duke does send grads into good business jobs.
The real issue is choosing a major if you want to go into business, and the school doesn’t offer traditional business majors.
That typically leaves economics…and what if you start taking micro and macro, and realize you don’t like econ? Then you will be in a bind…you could consider a math or statistical science major at Duke, or any type of quant econ/methods type majors that other schools may offer.
But none of those majors are going to have any courses cover marketing principles/concepts in great detail. Duke does have the finance minor…but would you be studying things you want to? Will a major in X and finance minor prepare you for the type of job you want?
You have plenty of time to think about this, and perhaps even take AP Econ next year.
Good luck.
