Answer:
The original price of the skateboard is $175
Explanation:
Say the original price is p
Discount is 20% and the skateboard is $140, say the skateboard price is s
Original price - 20% of original price = skateboard price
p - (20/100)p = $140
p - 0.2p = $140
0.8p = $140
Divide both side by 0.8
p = $140/0.8
p = $175
The original price is therefore $175
