Answer:
$300
Explanation:
The TV's regular price is 450 dollars, and we are looking for the sale price after a third of it gets marked off.
We first need to find 1/3 of 450.
![(1)/(3)* 450 = (450)/(3)=150](https://img.qammunity.org/2020/formulas/mathematics/middle-school/t2iyvrtt0ehgee1l2qitf4n8k0pzeew9kf.png)
One third of the original price is $150.
Now, we need to subtract 150 from 450.
![450-150=300](https://img.qammunity.org/2020/formulas/mathematics/middle-school/goom4trtpazbousu4tbl0ae15zzt3e4lu0.png)
So, the sales price of the TV would be $300.
Hope this helps!
