There are three blue seats for every two green seats in the cafeteria. if there are 80 total seats in the cafeteria, how many are blue?

Let G represents the green seats and B represents the Blue seats.

As per the statement:

There are three blue seats for every two green seats in the cafeteria.

⇒ for every two green seats, there are three blue seats.

then;

For every 1 green seats, there are 3/2 blue seats

i.e,

                 .....[1]

It is also given that if there are 80 total seats in the cafeteria.

then;

                          .....[2]

Substitute the equation [1] into [2] we get;

Combine like terms;

Multiply by 2/5 both sides we get;

Therefore, there are 32 blue seats.
