Target is having a huge winter season sale on all of their televisions. A 42in screen tv that usually retails at $580 is marked
torisob [31]

Answer: You do not because the tv costs $464.

Step-by-step explanation:

First find out how much 20% of 580 is:

= 20% * 580

= $116

The television was therefore marked down by $116. The current selling price is:

= 580 - 116

= $464

<em>Since you came with $450, you will not be able to buy the television as you would be short of the $464 required. </em>
