Question
An auto mechanic charges $50 to diagnose a problem and $25 per hour to repair the problem. If x represents the total number of hours worked and y represents the total charges, which equation represents this situation?
y = 25x + 50
y = 50x + 25
y = 50x – 25
y = 25x – 50
y = 25x + 50
y = 50x + 25
y = 50x – 25
y = 25x – 50

The total charges \( y \) consist of a fixed diagnosis fee of $50 and a variable repair fee of $25 for each hour worked. Therefore, the equation that represents this situation is:
\[ y = 25x + 50 \]
Here, \( 25x \) represents the cost of the repair based on the number of hours \( x \), and 50 is the flat fee for the diagnosis.
\[ y = 25x + 50 \]
Here, \( 25x \) represents the cost of the repair based on the number of hours \( x \), and 50 is the flat fee for the diagnosis.
