Answer:

z = 18.5

y = 15.5

x = 15.5

Step-by-step explanation:

Let

tulips = x

lilies = y

roses = z

x = y

z= x + 3 or y + 3

The equation is

0.18x + 0.27y + 0.55z = 17.15

Substitute x = y and z = y + 3 into the equation

0.18y + 0.27y + 0.55(y + 3) = 17.15

0.18y + 0.27y + 0.55y + 1.65 = 17.15

y = 17.15 - 1.65

= 15.5

x = y

x = 15.5

z = x + 3

= 15.5 + 3

= 18.5

Therefore,

z = 18.5

y = 15.5

x = 15.5
