Question

A television normally costs $1,420. Due to a store sale,the television is now $1,022.40. What was the percentage taken off of the television?

Answer 1

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 :-

$\dfrac{\text{New price - Previous price}}{\text{Previous cost}}\times100$

$=\dfrac{1420-1022.40}{1420}\times100\%\\\\=\dfrac{397.6}{1420}\times100\%\\\\=\dfrac{39760}{1420}\%\\\\=28\%$

Hence, the percentage taken off of the television= 28%
