A price rises from 80 dollars to 100 dollars. What is the percent increase?
Answer and explanation
Correct answer: D. 25 percent
- Step 1: The increase is 100 - 80 = 20 dollars. Step 2. Divide by the original price: 20 / 80 = 0.25. Answer: 25 percent. Why not the others: 20 percent divides by the new price, and the others do not match.
