Suppose that the average adult in the United States will work x number of days (rounded to the nearest day) to earn enough to pay for all of the household's leisure activities in that year. This number can be calculated by multiplying the average percent of household income spent on leisure activities by 365 (the number of days in a year). The bar graph shows the percent of income spent in various countries of the world. Use the graph to answer the question.

A. Germany, Britain, Japan, USA
B. China, Australia
C. China, Australia, France
