Write the linear equation that represents each situation.

it cost $12 to enter the fair and $3 per ride. write an equation for riding x rides

1 answer

To develop a linear equation for the total cost of entering the fair and riding \( x \) rides, we can break it down into two components:

  1. The cost to enter the fair, which is a fixed amount of $12.
  2. The cost of each ride, which is $3 per ride.

If you ride \( x \) rides, the total cost for the rides will be \( 3x \).

Putting both components together, the total cost \( C \) can be expressed as:

\[ C = 12 + 3x \]

This is the linear equation representing the total cost of entering the fair and riding \( x \) rides.
