130 blue spheres must be added to the cube to drop the concentration of yellow spheres to 5% of the total amount of spheres.
AAAaannndd the bot gets it wrong yet again!
20% of 150 = 30 yellow spheres
.05n = 30
n = 600
so we need 600 spheres in all to reduce the yellows to 5%
That means we need 450 more blues
