A new smartphone was originally priced at $250. It was first discounted by 15% off the original price. When Sarah purchased the smartphone, she received an additional 20% off the sale price. Sarah believes she got a total of 35% off the original price. Do you agree?

Be prepared to solve (show math) and explain if you agree or not and why!

• I agree.

• I disagree.

• I agree because 15% + 20% is 35% off.

• I disagree because it says 20% off the sale price, not the original price.
