Michael is coming home from a vacation. His gas tank has 1.5 gallons remaining, so he stops at a gas station 120 miles from his home. His gas tank holds up to 20 gallons of gas and his vehicle can travel 24 miles per gallon.
The gas station charges $2.10 per gallon of gas.
While filling his gas tank, Michael graphs a function relating the price he pays, p, to the amount of gas he purchases, 9
. Michael must purchase at least enough gas to get home.

answer:      

step-by-step explanation:

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.
