let's assign variables

Adults= A Children=C

We know that an adult cost 4$ so 4A

We know a kid cost 2$ so 2C

We know that 2C+4A= 6400

We know that there are A number of adults and C number of children

So, we know C+A= 2000

multiply it by two so that we can subtract the two equations.

We can subtract these two equations.

2c+4a=6400

-2C+2A=4000

2A=2400

-- ------

2 2

A=1200

Plug it into either of the equations

C+1200=2000

C=800

**1200 Adults and 800 children**
