Let:
100%---------------->24h
30%------------------>xh
Using cross multiplication:
Divide 132 by 16 to get 8.25 and you have to round up because you can’t fit 0.25 of people on a table.
Bart and David are correct.
Bart
6x(1+2/3^3)
6x * 1 = 6x
6x *2/3^3 = 4x^3
6x * 4x^3
David
x(6+4x^2)
x*6 = 6x
x*4x^2 = 4x^3
6x+4x^3
You combine those variables, then solve.
hope that helps :) ✨
