Question

Janet find a sweater on sale for 20% off. Original price is $50. She has a coupon for an additional 25% off the sale price. What is the final cost of the sweater?

Answer 1

Original price is $50. So it's 100%. It has 20% off, so:

50 - 100%

x - (100-20)%

Solving for x:

100x = 50*80

100x= 4000

x= 40

So, the price with discount is $40. She has a 25% off coupon, and now the total is 40$. So:

40 - 100%

x - (100-25)%

100x = 40*75

100x = 3000

x= 30$

So, the final cost of the sweter is $30.
