A store pays $ 23 for each umbrella. The store marks the price at 50%. What is the quantity of the mark?

The quantity of the mark is $11.5.

Step-by-step explanation:

The quantity of the mark can be determined by multiplying the cost of the umbrella by the markup percentage.

Thus,

The quantity of the mark = 23 × 50%

                                          = 23 × 50/100

                                           = 23 × 1/2

                                            = 23 × 0.5

                                             = $11.5

Therefore, the quantity of the mark is $11.5.

answer: 590

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.
