The following circle graph, or pie chart, illustrates the proportions of a man’s expenditures on recreation for a given year. For example, $13$ percent of his recreational expenditures were for his gym membership (a proportion of $0.13$).
Part 1: In the circle graph, a central angle of
degrees is required to form the sector for concerts.
Part 2: In a given year, if the man spends $\$416$ on swimming, then he is likely to spend
dollars on camping supplies.
Part 3: If the man classifies the gym membership, swimming, and camping supplies as athletic recreation, then
percent of his athletic expenses are for camping supplies.
