Answer:
165
Explanation:
What this ratio means is that for every 2 white carnations, there is 1 blue and 3 red.
We have 60 white, or 30 groups of 2
We have 3 red carnations for each group of two:
3 * 30 = 90
And we have 1 blue for each group of two:
30 / 2 = 15
So, our total number of carnations would be 90 + 15 + 60
Or: 165
