For a company picnic, Vijay ordered a box of fresh-baked gingerbread cookies and sugar cookies. He got 70 cookies in all. 28 of the cookies were gingerbread. What percentage of the cookies were gingerbread?

40%

Step-by-step explanation:

There are 70 cookies in total.

The gingerbread cookies number 28.

The percentage that are gingerbread will therefore be:

= Number of gingerbread/ Total number of cookies * 100%

= 28 / 70 * 100%

= 40%

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.

-2 is the right
