American Idol Mania!

Season 17 of American Idol ended earlier this year. At the end of the season finale, each of the three judges was asked to share his/her opinion about who should win the contest; Laine or Alejandro.  Each of the three judges responded and audiences around the country basically heard “Laine,” “Laine,” “Laine.”  If each judge answered either “Laine” or “Alejandro,” how many additional ways could the judges’ responses have been heard? 

Getting Ready for School

It’s probably a little strange to think that some students started school last week, some have another couple of weeks of summer vacation and still others are just continuing with their year-round school schedule!  The date of the beginning of the school year has been a topic of debate throughout the last decade (and even before) in many areas across the United States.  But the trend is definitely leaning towards starting school earlier rather than later.  Basically, in the last 10 years, the percent of public schools going back to school before Labor Day has increased by 63%

Each of the remaining six bedrooms each will be occupied by a pair of children, with six boys using three bedrooms and six girls using three bedrooms.
