Input the equation of the given line in slope-intercept form. The line with m = 2 and b = -4.

Answers

Answer:

y = 2x - 4

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 hours does he need to work to save the rest of the money for the video game? round to the nearest hour

Answers

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.
