Lin is selling floral arrangements. each arrangement uses 1 vase and 16 roses. each case costs lin $4.00. let c be the total cost of the arrangement and d be the cost of the 1 roses. write an equation that lin should use to find the total cost of each arrangement.

Step-by-step explanation:

Let

C -----> the total cost of the arrangement

D ----> the cost of each rose

we know that

The total cost of the arrangement is equal to the cost of one rose multiplied by 16 plus the cost of the vase

so

The equation that Lin should use to find the total cost of each arrangement is

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

the height of the surface increases from the center out to the sides of the road

it is c!
