First let's write our first proportion t=toys, c=candy and s=stickers. 6t + 4c + 12s = 22 things. (There are two stickers per toy [6t:2s])Now our new proportion isĀ : 5t + 6c + 10s = 21. I am unable to find the same proportion according to my math. This is as close as I can get you. I hope I helped.
