Answer:
20% discount
Step-by-step explanation:
you need to find how much money was taken off the price so you do 35-28 and you get 7 dollars. Now that you know that 7 dollars were taken off of the original price, you have to find what percent of 35 dollars is 7 dollars. To do this you must do 7/35, which simplifies to 1/5. 1/5 as a percentage is 20%, so the discount is 20%.
