A store is having a 20% off sale Michael says that he can find the sale price of an item that has a regular price of p dollars by evaluating the expression 0.8p Susan says that she can find the sale price for the same item by evaluating the expression p-0.2p who is correct
Accepted Solution
A:
They both are correct. Michael created an expression that shows what percent you are paying for the item by taking 100% of it minus 20%.
Susan is starting with full price and taking away 20% of the price which would leave you with the sale price.
