4/28/08 - Problem of the Week (Problems)

And Then There Were Two - The Solutions
June 9, 2008

Barrack Obama:
(2180 – 2118)/2118 × 100 = 2.927%

John McCain:
(1504 – 1091)/1091 × 100 = 37.855%

37.855 – 2.927 = 34.9%

(30,668,436 – 17,538,378)/17,538,378 × 100 = 74.9%

If 10 percent were undecided that leaves 90 percent to divide between McCain and Obama. Let’s let x equal the percent of votes for Obama and x – 2 equal the percent of votes received by McCain.

x + x – 2 = 90

2x = 92

x = 46 percent voted for Obama
