If 2 gallons of paint is $19.20, 1 quart is?

$2.40

Step-by-step explanation:

2 gallons = $19.20

1 quart = ?

Convert quart to gallons.

1 quart = 0.25 gallons

2 gallons = $19.20

0.25 gallons = x

Cross multiply.

19.20 × 0.25 = 2x

4.8 = 2x

x = 2.4

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.

answer: 5100 just subtract
