Alex sells hotdog at $5 at the Piazza on the Christmas day (Dec.
25). As the supplier requires a firm order by the afternoon of Dec.
24, Alex must make a commitment before the demand is known. The
supplier's wholesale price is $3 per unit of hotdog. Alex forecasts
that the daily demand is normally distributed with mean 220 units
and standard deviation 50. Any hotdog left by the end of Christmas
day can be sold for only $2 per unit.
How many hotdog(s) should Alex order from the supplier on Dec.
24? Choose the closest answer if needed because the supplier sells
only packs of 20.
