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 the television? ( Please show me the work, thanks)

Answer 1

Answer:

The discount is 28%

Step-by-step explanation:

The original value of the TV is $1,420, that is the 100% of the value. If we want to find the discount value we could calculate as follows:

$D=1-(\frac{price with discount}{full price} )\\D=1-\frac{1022.40}{1420} \\D=1-0.72\\D=0.28$

The discount is 28%

Answer 2

The TV is 28% off. You can verify this by dividing 1022.4 by 1420 and getting 0.72. That's how much of the price you have to pay.

So you just subtract .72 from 1 to .28
