Answer:
skew
Step-by-step explanation:

The <em><u>correct answer</u></em> is:
C.) old price was $170, new price is $159.12
Explanation:
The original price was $136. For a 25% markup, this means the amount of markup is 0.25(136) = 34. This makes the new price 136+34 = $170.
When they mark the price down to a 17% markup, this means the price is 0.17(136)+136 = 23.12+136 = $159.12.
