The bike costs $200 and is reduced by 30%
The cost price = $200, percentage loss is 30% or 0.3
We calculate how much the bike's cost is reduced by multiplying its original price with the factor 0.3 = 200 * 0.3 = 60
1. That means it was reduced by $60
Since $60 was removed from the original price, the sale price becomes $200 - $60 = $140
2. Therefore it costs $140 in the sale.
