X = the number of months the tire was used
y = the thickness of the tire tread

y = -(3/7)x + 20

The next question: Substitute x for 49 (the number of months the tire was used) and solve for y.

Jordan saved 4/5 of the amount he needs to buy a $80 video game. If he earns $7.75 per hour by working at a pizza shop, how many
Aleksandr [31]
Amount of money saved by Jordon for the video game = (4/5) * 80
                                                                                        = 4 * 16 dollars
                                                                                         = 64 dollars
So
The amount of money that
Jordan needs to earn more for buying the video game = (80 - 64) dollars
                                                                                       = 16 dollars
Amount earned by Jordan per hour working at a pizza shop = $7.75
Let us assume the number of hours Jordan needs to work to save the rest of the money for the video game = x
Then
7.75x = 16
x = 16/7.75
   =  2.06 hours
So it can be said that Jordan has to work 3 hours to save the rest of the money for the video game. If Jordan works 2 hours then he will be short of the required amount. If Jordan works for 3 hours he will have some excess amount in his hand after saving for the video game.
