You and your best friend Josh, each want to purchase a video gaming system the costs $200 you have $100 and save five dollars each week Josh has $50 in save $10 each week write the equation for you and Josh.

For you : 100+5x=200

For Josh : 50+10x=200

Step-by-step explanation:

Given : Cost of video game.= $200

Money you have = $100

Money you add each week = $5

Let x be the number of week, the money( in $) you have after x weeks = 100+5x

Josh has $50 in save $10 each week , then money( in $) Josh has after x weeks = 50+10x

Required equations :

For you : 100+5x=200

For Josh : 50+10x=200

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
