A bike is on sale for $135. The original price of bike is 135
Solution:
Given that bike is on sale for $ 135
The mark down price is 20 %
We need to find the original price of the bike
Hence we can say that,
Selling price of bike = 135
Mark down price = 20%
Original price of bike = ?
The cost price is given as:
![Original price = selling price * (100)/(100 - markup percentage)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/e0imxvrntp395ifh9rn81h2izop924c48x.png)
By substituting the values we get,
![original price = 135 * (100)/(100-20)\\\\= 135 * (100)/(80)\\\\= 168.75](https://img.qammunity.org/2020/formulas/mathematics/middle-school/v0jzamsgblvtau5333j9n25cbugzy2dv91.png)
Hence the original price of bike is $ 168.75
