Part A) c + r = 204
Part B) c/6 and r/6, since Allison wants to divide the number of carnations and the number of roses to each shop, she would have to divide the carnation into 6 equal groups and the roses into six equal groups, and give one group to each flower shop
Part C) Each shop will receive 4 carnations and 2 roses since you have to divide 24 by 6 and 12 by 6
Part D) There will be 2 bouquets, each bouquets will have 2 carnations and 1 rose since he only has 4 carnations and 2 roses, and both can be divided by 2 to get the number of carnations to roses for each bouquets
Hope this helped tell me if you got confused
