A family went to a baseball game. They parked the car in a parking lot which charged ​$20. The cost per ticket was ​$27. Write an equation for the total cost of going to the baseball​ game, where y is the total cost and x is the total number of people. If the family spent ​$236​, how many people went to the​ game?

Answer:

[tex]y=27x+20[/tex]

8 people went to the game.

Step-by-step explanation:

Let x represent number of tickets.

We have been given that the family parked the car in a parking lot which charged ​$20. The cost per ticket was ​$27.

The cost of x tickets would be [tex]27x[/tex].

The total cost of going to baseball game would be equal to cost x tickets plus parking cost that is [tex]27x+20[/tex].

Therefore, the equation [tex]y=27x+20[/tex] represents the total cost (y) of going to the baseball​ game.

To find the number of people who went to game, we will equate total cost with 236 as:

[tex]236=27x+20[/tex]

[tex]236-20=27x+20-20[/tex]

[tex]216=27x[/tex]

[tex]\frac{216}{27}=\frac{27x}{27}[/tex]

[tex]8=x[/tex]

Therefore, 8 people went to the game.
