Answer
Answer:
c. 20%
Explanation:
Step1: Calculate ticket - related costs
The cost of the airline ticket is $69. The sales - tax on the ticket is $69\times0.15 = 10.35$. The baggage fee is $20. So the total cost of the ticket and related fees is $69 + 10.35+20=99.35$.
Step2: Calculate taxi cost without tip
The taxi travels 8 miles at a rate of $2.50 per mile, so the taxi fare without tip is $2.5\times8 = 20$.
Step3: Calculate total cost of ticket and taxi without tip
The total cost of the ticket and taxi without tip is $99.35 + 20=119.35$.
Step4: Calculate tip amount
Clovis spent a total of $123.35. So the tip amount is $123.35−119.35 = 4$.
Step5: Calculate tip percentage
The tip percentage is $\frac{4}{20}\times100%=20%$.
