You sell tires for $65 each at your automotive service shop. At this price, what does it cost to purchase a set of 4 tires, not including tax?

$69
$105
$260
$280
$325

A set of 4 tires cost $260.

Step-by-step explanation:

It is given that each tire is sold for $65. In order to find a set of 4 tires, you have to multiply it by 4 :

1 tire = $65

4 tires = $65×4

= $260

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
