Homework Assignment #6, Due Wednesday February 14
1. Three friends, returning from the movie Friday the 13th Part 65, stopped to eat at
a restaurant. After dinner, they paid their bill and noticed a bowl of mints at the
front counter. Sean took 1/3 of the mints, but returned four because he had a
momentary pang of guilt. Faizah then took 1/4 of what was left but returned
three for similar reasons. Eugene then took half of the remainder but threw two
that looked like they had been slobbered on back into the bowl. (He felt no
pangs of guilt - he just didn’t want slobbered-on mints). The bowl had only 17
mints left when the raid was over. How many mints were originally in the bowl?
