Answer by greenestamps(13200)   (Show Source): You can put this solution on YOUR website!

a.  c = number of carnations
b.  12-c = number of roses (because the total number of flowers is 12)
c.  0.85c  (the carnations cost $0.85 each)
d.  1.5(12-c)  (the roses cost $1.50 each)
e.  (0.85c)+(1.5(12-c)) = 0.85c+18-1.5c = 18-0.65c  (represents the total cost of the 12 flowers)
f.  18-0.65c = 14.75
    0.65c = 3.25
    c = 5
g.  The bouquet that costs $14.75 contains c = 5 carnations and 12-c = 7 roses
