Dena said, "To find 20% of a number, I should multiply by 0.20. So the sale price of an item will be 0.20p."
Which statement best describes Dena's reasoning?
1. Dena is correct.
2. Dena needs to subtract 0.20p from the regular price=p.
3. Dena should calculate the sale price as 20p and then divide by 100.
4. Dena is trying to solve a inconceivable problem because it doesn't mentions what the regular price is.​
