Answer

Explanation:

Step1: Calculate old markup value

The original cost is $136. The old markup is 25% of 136. So the old - markup value is $136\times0.25 = 34$.

Step2: Calculate old selling price

Using the formula selling price = original cost+markup value, the old selling price is $136 + 34=170$.

Step3: Calculate new markup value

The new markup is 17% of 136. So the new - markup value is $136\times0.17 = 23.12$.

Step4: Calculate new selling price

Using the formula selling price = original cost+markup value, the new selling price is $136+23.12 = 159.12$.

Answer:

C. old price was $170; new price is $159.12
