Question

Clovis wants to make a surprise visit to his uncle who lives out of town. He purchases an airline ticket for $69. There is a 15% sales tax on the price of the airline ticket. In addition he must pay a baggage fee of $20. When he arrives at the airport, Clovis takes a taxi to his uncle's house which is 8 miles from the airport. The taxi fee is $2.50 per mile. If Clovis has spent a total of $123.35 for the airline ticket and taxi, at what percent of his fare did Clovis tip the taxi driver?
a.
10%
b.
15%
c.
20%
d.
25%

Answer 1

Airline cost: 69 + 15% of 69 (10.35) + baggage 20 = 99.35.
Total spent 123.35, so taxi payment = 123.35 − 99.35 = 24.
Taxi fare before tip = 8 miles × $2.50 = 20, so tip = 24 − 20 = 4.
Tip percent = 4/20 = 0.20 = 20%.

Answer: c.
