nina paid the bill for dinner with her family. the total cost of the food was $65, and the restaurant added an 8 percent sales tax, $5.20, to the bill. nina wants to pay a 15 percent tip on the total bill including sales tax. what is the amount of the tip?\n$8.97\n$9.75\n$10.53\n$14.95
Answer
Explanation:
Step1: Calculate total bill
The cost of food is $65 and sales - tax is $5.20. So the total bill before tip is $65 + 5.20=70.20$.
Step2: Calculate tip amount
The tip is 15% of the total bill. We find 15% of 70.20. Using the formula for percentage $p=\frac{15}{100}\times70.20 = 0.15\times70.20=10.53$.
Answer:
$10.53$
