Uri can blow up up a balloon in 5 seconds and Lee can blow up a balloon in 6 seconds. Uri takes 3 seconds to tie each balloon and Lee takes 4 seconds to tie each balloon. Together they blew up and tied three bags of balloons in 14 minutes. How many balloons were in each bag?

14 minutes = 840 seconds.
In 840s, Uri blows and ties 840/(5+3) balloons = 840/8 = 105 balloons.
In 840s, Lee blows and ties 840/(6+4) balloons = 840/10 = 84 balloons.
Total balloons = 105+84 = 189.
Divide by 3 bags --> 189/3 = 63 balloons per bag!
