c = the number of dozens of carnations in the order
A floral shop receives a $612 order for roses and carnations. The prices per dozen for the roses and carnations are $18 and $15, respectively.
18r + 15c = 612
The order contains twice as many roses as carnations:
r = 2c
by solving the system of equations:
18r + 15c = 612
r = 2c
we find:
r = 24 dozens of roses
c = 12 dozens of carnations
