Jordan saved 4/5 of the amount he needs to buy a 80.00 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?

2.06 hours

Step-by-step explanation:

Money saved by Jordan to buy a $80 video game =   × =

So Jordon needs 80 - 64 = $16 more to get the video game

He gets $7.75 per hour by working, so assuming the number of hours to be x he needs to work to get $16, we can write it as:

Therefore, Jordan needs to work at least for 2.06 hours to save the rest of the money for the video game.

step-by-step explanation:

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
