Answer: 80%
Explanation:
Let's use the rule of 3 here.
We know that the original price or 100% of the price was $300
($300 - 100%)
We want to know what percent of the original price (let that be our x) is the bike selling for now that costs $240.
($240 - x)
Let's do our chart.
![(300)/(240)=(100)/(x)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/b30s6uzvvidtzgnfg01x0mpei4dltnunr3.png)
Solve for x.
![x=(240*100)/(300)\\ x=80](https://img.qammunity.org/2021/formulas/mathematics/middle-school/h088i3ozxvn4ywslckl7q7r8tjcade0x2o.png)
The bike is selling for 80% of the original price.
