Problem
Kyle's birthday party in 2007 cost dollars per person and people attended. In 2008, the cost per person doubled and the number of people attending the party also doubled. What is the ratio of the total cost of the party in 2007 to the total cost of the party in 2008? Express your answer as a common fraction.
Solution
The cost increased by a factor of 2 due to the increase in cost per person and by an additional factor of 2 due to the increase in number of people. In total, the cost increased by a factor of 4, so the ratio of the cost of the party in 2007 to the cost of the party in 2008 is .
Final answer
\frac{1}{4}
