The initial discount ranges from 0.9 to 0.92 of the new condition price. With additional 5%-9% discount we get the possible discount range as:
1) 0.92*0.95 = 0.874 (the smallest possible discount – 12.6%)
2) 0.9*0.91 = 0.819 (the largest possible discount – 18.1%)
With new condition price of $160 we get the following difference in price assuming the smallest and largest possible discounts:
1) $160*(1-0.874) = $20.16
2) $160*(1-0.819) = $28.96
In both cases, the difference before and after discounts is greater than $20. The answer is A.
