Answer: 28%
Step-by-step explanation:
Given : The normal price of television = $1,420
i.e. Previous price= $1,420
Due to a store sale, the price of television now = $1,022.40.
i.e. New price = $1,022.40.
Now, the percentage taken off of the television :-
[tex]\dfrac{\text{New price - Previous price}}{\text{Previous cost}}\times100[/tex]
[tex]=\dfrac{1420-1022.40}{1420}\times100\%\\\\=\dfrac{397.6}{1420}\times100\%\\\\=\dfrac{39760}{1420}\%\\\\=28\%[/tex]
Hence, the percentage taken off of the television= 28%
