10. Giulietta is free from work every Sunday (and no other day). Romeo works on a cruise ship: he stays at sea for 9 days, then has a day off before boarding again for another 9 days, and so on. Today, Wednesday, November 23, 2016, Romeo is on land and will board tomorrow. How many days can Giulietta and Romeo spend together from now until November 23, 2017?
(A) 8
(B) 5
(C) 7
(D) 6
(E) 4
Problem 10. The answer is (B).

Romeo has a day off every 10 days, and his first day off is a Wednesday. His days off fall, in order, on Wednesday, Saturday, Tuesday, Friday, Monday, Thursday, Sunday, and then start over from a Wednesday. Romeo and Juliet will meet once every 70 days, and the first time will be in 60 days. Given that there are 365 days in a year, the meetings will occur on days 60, 130, 200, 270, and 340, and there will be a total of 5 meetings.
