At the rate that Darla is reading, how long will it take her to read 540 pages?

A 18 hours
B15 hours
C 12 hours
D9 hours

B: 15 hours

Step-by-step explanation:

Since Dara spends 2 hours reading 72 pages, we can conclude that she spends 1 hour reading 36 pages.

Since we are finding how long it would take for her to read 540 pages, we would divide 540 by 36, which is 15.

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.
