Afair owner made 18 dollars when a group of three entered which is the rate of fair per person

Let's start with an example.

At the market, 8 batteries cost $10.

How much do 6 batteries cost?

We’re trying to find the cost of 6 batteries.

Batteries                        Cost

8 / 8 = 1                         $10/ 8 = $1.25

If 8 batteries cost $10, then 11 battery costs $1.25.

Batteries                        Cost

8                                     $10

1 x 6                               $1.25  x 6        

6                                    $7.50        

So, 6 batteries cost $7.50.

Back to your question...

We are trying to find the rate of fair which means the fair price for 1 person

Fair                                 Person

18/3                                  3/3

6                                        1

So, the fair owner will make $6 for 1 person.

Hope this helped! Good luck!
