Football Problem of the Week

OPTION 1:
The minimum starting annual salary for rookies in the NFL is $295,000. The minimum annual salary is $370,000 for second year players and $445,000 for third year players. For a player earning the minimum salary for their experience, what is the positive difference between the percent increase the $75,000 represents from the first to second year and the percent increase the $75,000 represents from the second to third year? Express your answer as a decimal to the nearest tenth.

OPTION 2:
There are 32 teams in the NFL. Sixteen of the teams are in the American Football Conference (AFC) and the other 16 teams are in the National Football Conference (NFC). At the beginning of the season, Julia tried to predict the teams that would be in each conference's championship by randomly drawing 4 teams (2 AFC teams and 2 NFC teams) from a hat. What is the probability that the 4 teams she selected are the same four teams that will be in the conferences' championships? Express your answer as a common fraction.

OPTION 3:
In football, teams can score 6 points with a touchdown, 3 points with a field goal or 2 points with a safety. Additionally, after a touchdown, teams can score 1 bonus point with a field goal kick or 2 bonus points with a 2-point conversion. The final score of a particular football game was 13 to 11. If every touchdown is followed with a successful bonus point attempt (1 or 2 points), how many different scoring combinations could have resulted in the losing team's 11 points?

1/5/09 Inauguration POW

Option 1:
The 2009 inauguration is expected to see record levels of attendance. Lyndon B Johnson’s inauguration currently holds the record for attendance at 1.2 million people. Originally, attendance for the 2009 inauguration was projected to be as high as 5 million. Now, based on more accurate data, the projected attendance is around 2 million. What is the positive difference between the originally estimated percent increase over the current record attendance and the newly estimated percent increase over the current record attendance? Express your answer to the nearest whole number.

Option 2:
The National Mall is 300 acres. It stretches 1.9 miles from the Capitol building to the Lincoln Memorial. This will be the first time in history that the entire mall will be open for an inauguration. If attendance is the estimated 2 million people and all of the people spread out evenly over the mall, how many square feet will each person get? Note that 1 acre is equal to 43,560 square feet. Express your answer as a decimal to the nearest tenth.
