      Hi ArtisticPython7469,

      Thanks for your question!

      In this situation, let's say that the 100w lamps are the variable x. The equation is :

      $$x \leq \frac{2}{3} \ sum$$

      Here the sum is the total number of lamps. You can write as the sum of all the variables that represent the number of a type of lamp. Also, the ≤ is used because x at most is equal as the 2/3 of all the lamps.

      Also, here's our concept sheet about the inequalities :

      I hope that helps and feel free to write us again!
