Answer:
The number of arrangements she made was:
2 small arrangements
3 medium arrangements
4 large arrangements
Step-by-step explanation:
There are 3 sizes of arrangement
Let r = roses
d = daisies
c = chrysanthemums
Each small arrangement contains one rose, four daisies, and four chrysanthemums.
r + 4d + 4c
Each medium arrangement contains two roses, four daisies, and five chrysanthemums.
2r + 4d + 5c
Each large arrangement contains four roses, six daisies, and six chrysanthemums.
4r + 6d + 6c
We are told that
One day, the florist noted that she used a total of 24 roses, 44 daisies, and 47 chrysanthemums in
Rearranging the equations,
Where s = small arrangements
m = medium arrangements
l = large arrangements
we have:
s + 2m + 4l = 24 ........Total number of roses
3s + 4m + 8l = 50 ....... Total number of daisies
3s + 6m + 6l = 48 ......... Total number of Chrysanthemums
From the above:
We can see that we have 3 equations and to solve it, we use Matrix method to solve this question because this is a 3 system (3 × 3) Matrices
I am unable to type the Matrices solution here, so please find it attached to this answer.
