Here is a double number line showing that it costs $3 to buy 2 bags of rice: A double number line with 6 evenly spaced tick marks. The top number line is labeled "cost, in dollars." The number 0 is indicated on the first tick mark and 3 is on the second. The bottom number line is labeled "rice, number of bags." The number 0 is indicated on the first tick mark and 2 is on the second. At this rate, how many bags of rice can you buy with $12? Find the cost per bag. How much do 20 bags of rice cost?

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: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
