The total cost for one person to go on 8 rides is $

Answer 1

To write the equation that represents the total cost (y) based on the number of rides (x), we can consider the cost of the ticket and the cost of each ride.

1. The cost of the ticket is $20.
2. Each ride costs $4.50.

The total cost \( y \) can then be represented as: \[ y = 20 + 4.50x \]

Now, to calculate the total cost for one person to go on 8 rides, substitute \( x = 8 \) into the equation:

\[ y = 20 + 4.50(8) \]

Calculating the cost of the rides: \[ 4.50(8) = 36 \]

Now, substitute back into the equation:

\[ y = 20 + 36 = 56 \]

So, the total cost for one person to go on 8 rides is \( \text{$}56 \).

Final answers:

• The equation for the cost of tickets is: \( y = 20 + 4.50x \)
• The total cost for one person to go on 8 rides is \( \text{$}56 \).
