Problem: Income inequality has become a hotly debated topic globally. According to the CIA World Factbook, U.S. income inequality ranked 41st highest among 156 countries in 2017 (i.e., 74% of countries have a more equal income distribution). According to the Congressional Budget Office, the top 1% of income households earned about a 9% share of the pre-tax income in 1979, versus 19% in 2007 and 17% in 2014. For after-tax income, these figures were 7%, 17%, and 13%, respectively. These figures indicate the share of income earned by top earners more than doubled between 1979 and 2007, then fell somewhat following the Great Recession, and the higher tax rates and re-distributive policies applied by President Barack Obama in 2013 (i.e., expiration of the Bush Tax Cuts for the top 1% and subsidies for lower income persons via the Affordable Care Act). Recasting the 2012 income using the 1979 income distribution (representing the more egalitarian 1950-1980 period), the bottom 99% of families would have averaged about $7,100 more income. Income inequality in the United States has grown from 2005 to 2012 in more than 2 out of 3 metropolitan areas.

How many percentage points less after-tax income did the top 1% have than pre-tax income in 2007?
Answer: 2

Problem: Japan signed the peace treaty with 49 nations in 1952 and concluded 54 bilateral agreements that included those with Burma (US$20 million 1954,1963), the Republic of Korea (US$300 million 1965), Indonesia (US$223.08 million 1958), the Philippines (525 million US dollars/52.94 billion yen 1967), Malaysia (25 million Malaysian dollars/2.94 billion Yen 1967), Thailand (5.4 billion Yen 1955), Micronesia (1969), Laos (1958), Cambodia (1959), Mongolia (1977), Spain ($5.5 million 1957), Switzerland, Netherlands ($10 million 1956), Sweden and Denmark. Payments of reparations started in 1955, lasted for 23 years and ended in 1977. For countries that renounced any reparations from Japan, it agreed to pay indemnity and/or grants in accordance with bilateral agreements. In the Joint Communique of the Government of Japan and the Government of the Peoples Republic of China (1972), Peoples Republic of China renounces its demand for war reparation from Japan. In the Soviet-Japanese Joint Declaration of 1956, the Soviet Union waived its rights to reparations from Japan, and both Japan and the Soviet Union waived all reparations claims arising from war. Additionally, Ceylon (now Sri Lanka), under President J. R. Jayewardene, declined war reparations from Japan.

How many millions of dollars (USD) did Japan pay to Burma, the Republic of Korea, and Spain combined?
Answer: 325.5

Problem: Hoping to rebound from their divisional road loss to the Packers, the Vikings' Week 11 opponent was the Oakland Raiders, who had former Vikings quarterback Daunte Culpepper under center. After a 79-yard pass from wide receiver Sidney Rice to Visanthe Shiancoe on the first play from scrimmage, the Vikings scored on the very next play on a 10-yard run from Chester Taylor. This was followed by a safety when Culpepper was penalized for intentional grounding in his own endzone. Two plays after the ensuing free kick, the Vikings fumbled the ball just inside Oakland territory, allowing the Raiders to set up a 42-yard field goal for Sebastian Janikowski. On the next drive, the Vikings restored their nine-point lead as kicker Ryan Longwell hit a 30-yard field goal on the first play of the second quarter. A short Oakland drive culminating in 10-yard touchdown pass from Culpepper to tight end John Madsen, followed by another Janikowski field goal, saw the Raiders take the lead for the first time. Four plays later, Minnesota regained a six-point lead on a 38-yard touchdown run from Taylor, but field goals of 42 and 49 yards from Janikowski meant the first half ended with the scores level at 19-19. The Vikings recorded the only score of the third quarter on a 38-yard field goal from Longwell, though they did finish the period on the Raiders' 6-yard line, allowing Taylor to run in his third touchdown on the opening play of the fourth quarter, the first time in his career that he scored three touchdowns in one game. A 52-yard field goal from Janikowski narrowed the margin to 7 points with less than three-and-a-half minutes to play, and after forcing the Vikings to punt just inside the two-minute warning, they had one last chance to level the scores. On the first play of the drive, Culpepper threw the ball in the direction of Justin Fargas, who tipped it up, allowing Chad Greenway to come up with an interception; he went to ground with the ball, but inexplicably got up and attempted to advance it, which allowed left tackle Barry Sims to force a fumble, recovered by right guard Paul McQuistan. That enabled the Raiders to extend their drive, but although they managed to get into Vikings territory, a false start penalty meant Culpepper had to attempt a Hail Mary pass on the final play, but it came up short, giving the Vikings a 29-22 win.

How many total points were scored in the game?
Answer: 51

Problem: In week 12, the Packers traveled to Qwest Field to play the Seattle Seahawks. It was the Packers' second Monday Night Football game of the season. Green Bay held the lead at the end of the first half, with a touchdown run from Ahman Green and a fumble return for a touchdown by Abdul Hodge, who recorded his first NFL start. Seattle kicker, Josh Brown kicked four field goals in the first half. In the second half, the Packers were able to increase the lead to nine points as quarterback Brett Favre threw a 48-yard touchdown pass to Donald Driver. Seattle would decrease the Packers lead to two points when quarterback Matt Hasselbeck threw a 23-yard touchdown pass to receiver D.J. Hackett. The Seahawks would take the lead in the fourth quarter with another touchdown pass from Matt Hasselbeck. Packers kicker Dave Rayner kicked a 34-yard field goal to decrease the Seahawks lead to three points, but on the next possession, Hasselbeck completed his third touchdown pass to Jerramy Stevens. The Packers were unable to score in the closing minutes of the game as Brett Favre is intercepted twice. Seattle Seahawks running back, Shaun Alexander rushed 40 times for 201yards, averaging about five yards per carry. Matt Hasselbeck completed 17 of 36 passes for 157yards and three touchdowns. He was also intercepted three times, two of them by cornerback Charles Woodson. Brett Favre completed 22 passes in 36 attempts for 266yards. He recorded a touchdown and three interceptions.
