Question

Joshua goes out to lunch. The bill, before tax and tip, was $19.50. A sales tax of 6%

was added on. Joshua tipped 17% on the amount after the sales tax was added. The
total cost of the meal plus tip and tax was more than the cost of the bill by what
percent? Round to the nearest whole number.

Answer 1

24.02%

Explanation:

19.5 increase 6% =

19.5 × (1 + 6%) = 19.5 × (1 + 0.06) = 20.67

20.67 increase 17% =

20.67 × (1 + 17%) = 20.67 × (1 + 0.17) = 24.1839

Percentage of increase = |19.50 - 24.1839|/19.50 = 4.6839/19.50 = 0.2402 = 24.02%

4.6839 ÷ 19.5 = 0.2402 = 24.02%
