Tracy goes on a 3 day and night school band trip. There is no cost for travel and each band member only pays half the cost of the hotel room. However, each person is responsible for the cost of their own meals. His portion of the hotel bill is $49 per night and Tracy leaves a 10% tip for the maid service. Before tax, Tracy spends $32 per day on eating out plus 15% of this amount in tips. If Tracy spends a total of $280.74 on the band trip, what percent tax was Tracy charged on his food?
The hotel costs 3 × $49 = $147, and the 10% maid-service tip is $14.70. Food costs $3 × $32 = $96 before tips and tax; the 15% food tip is $14.40. Subtracting these amounts from the $280.74 total leaves $8.64 in food tax, and $8.64 ÷ $96 = 0.09, or 9%. The correct choice is 9%.
