The amount of Hanna's bill for a food order was $50. Hanna gave a tip of 20% of the amount of the bill. What is the amount, in dollars, of the tip Hanna gave?
Correct answer: A. 10
- A. 10
- B. 12
- C. 15
- D. 20
Explanation
The correct answer is 10. It's given that the amount of Hanna's food order was $50 and that Hanna gave a tip of 20% of the amount of the bill. 20% of 50 can be calculated as (20/100)(50), which yields 1000 / 100, or 10. Therefore, the amount, in dollars, of the tip Hanna gave is 10.
