Which answer is the best explanation for how to check to see that the difference has been calculated correctly for this problem?
76.5 – 4.32 = 72.18
a.
add the first and second numbers to get the difference.
b.
add the difference to the second number to get the first number.
c.
subtract the second number from the difference to get the first number.
d.
add the first number and the difference to get the second number.

it is b)

hope this : )

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.
