Question

I need help on this​

Answer 1

0,85*0,9=0,765 same with the other that means that the price will be reduced by 23,5 percent (1-0,765). And the change factor för 25% is 0,75 so you will get the best price with 25%

Answer 2

25% off

Explanation:

Let's say we have an item that costs $20

1: 15% off then 10% off

100-15=85

20*0.85=17

100-10=90

17*0.9=15.3

2: 10% off then 15% off

100-10=90

20*0.9=18

100-15=85

18*0.85=15.3

3: 25% off

100-25=75

20*0.75=15

The best deal is 25% off

Hope this helps!
