Answer: 28 %
Explanation:
The original cost of the television is 1420$. The discounted price is instead 1022.40$. In order to find the percentage taken off, we must calculate the difference between the original price and the final price, and then divide the result by the original price:
[tex]\frac{1420 -1022.40}{1420}=0.28[/tex]
And to calculate the percentage, we simply multiply by 100:
[tex]0.28 \cdot 100 =28 \%[/tex]
