As a check,

We don't get the exact thing on both sides, but the two sides are close enough. We have rounding error due to P2 being not exact.

Answer:
final price of skateboard will be $119
Step-by-step explanation:
Given that:
Purchasing price = $100
Mark up = 40%
So the mark up price would be:
= Original price + 40%(Original price)
= $100 + 40%($100)
= $100 + 40
= $140
Now when store is having a sale everything will be 15% off so:
Sale price of skate board will be:
= $140 - 15%(140)
= $140 - 0.15(140)
= $140 - $21
= $119
So the final price of skateboard will be $119
i hope it will help you!
