Jeff sells the New York Times Sunday newspaper at a city corner near several churches.

He sells each newspaper for $$6\mathrm{.}50$ after purchasing them for $$4\mathrm{.}00.$ Any unsold

newspaper can be returned to the New York Times for a $$0\mathrm{.}75$ credit. Jeff expects

demand on Sunday to be $75,100,125,$ or $150$ newspapers and would like to order one

of these four quantities from the New York Times. If Jeff orders $100$ papers from the New

York Times and the Sunday demand is for $150$ papers, what will the profit be$?$
