Round to the nearest tenth of a percent. % of 1000 sales is 100 sales.
A. 15%
OB.5.5%
OC. 10%
D.50%

C. 10%

Step-by-step explanation:

This question can be solved using a rule of three.

1000 sales is 100% = 1.

100 sales is 100*x%.

So

1000 sales - 1

100 sales - x

1000x = 100

x = 100/1000

x = 0.1

0.1*100 = 10%

So the correct answer is:

C. 10%

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.
