Which of the following is most likely the next step in the series?
A.
B.
C.
D.

A

Step-by-step explanation:

Note that the dots in both the upper and lower row increase by 1

The 3rd diagram has 4 dots in the upper and 3 in the lower , then

the next diagram should have 5 dots in the upper and 4 in the lower

This is the case in diagram A

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.
