Let’s call the # of blue balloons = B and the # of green balloons = G
We know that B + G = 21 balloons in total, and that the ratio of B:G = 4:3
From there, we can see that if B/G = 4/3, 3B = 4G
Now, let’s substitute one for the other - since B +G = 21 → B = 21 - G
3 * (21 - G) = 4G → 63 - 3G = 4G → 63 = 7G → 9 = G
Since B + G = 21 and G = 9, there were 12 blue balloons at Kali’s party.
