Question

hich is a better deal on a $50 item: 45% off original price or 30% off, plus an additional 20% off at the register? Your answer must include your math calculations.

Answer 1

45% off would be 27.50 and then you would do 30% off of 27.50 and it would be 19.25 and then 20% off of 19.25 and that would be 15.40

Explanation:

Answer 2

first option: 45% off: 50.00-0.45*50.00=27.50 dollars
second option: after 30% off, the price is 50.00-0.3*50=35.00.
20% off 35.00: 35.00-0.2*35.00=28.00
the first option is a better deal.
