Marlo is painting his bedroom walls. The room is rectangular in shape with width w and length 2. Marlo knows he can find the area A of the four walls to be painted (not accounting for doors or windows) using the formula A = 21h + 2wh, where h is the height of each wall that is painted. The label on the paint can gives the area that the paint is expected to cover but Marlo is unsure how high up each of the walls he can paint. Which of these shows the formula rewritten so that it has been solved for h?

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.
