After a 20% discount, you pay $140 for a skateboard. What was the original price?

The original price of the skateboard is $175

Step-by-step 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

168

Step-by-step explanation:

20% of 140 is 28

140 + 28 = 168
