To accurately interpret the meaning of the initial amount in the equation provided, we need to understand the structure of the equation, which typically has the form:
\[ y = mx + b \]
Where:
- \( y \) is the total charge.
- \( m \) represents the hourly charge.
- \( x \) is the number of hours.
- \( b \) is the initial (fixed) amount charged for the repair.
If the initial amount is given as $75, for example, it would mean that the technician charges a fixed amount of $75 regardless of the time spent on the repair. Therefore, in this context, the correct answer would be:
c. it means the technician charges a fixed amount of $75 for the repair.
