A florist makes three special flower arrangements. One uses five lilies. The second uses four lilies and five carnations. The third uses three daisies and four carnations. Lilies cost ​$1.85 ​each, carnations cost ​$0.90 ​each, and daisies cost ​$1.10 each. Complete parts ​(a​) through ​(c​) below.

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
