Explain the significance of the equation \( y = 50x + 20 \), which represents the hourly cost of a car repair.

The '20' is what it costs you to drive your car into the garage and say "Good morning", before they ever start working on it. As you can see, the cost (y) is 20 even if the number of hours (x) is zero.
The '50' is the added cost for each hour a mechanic spends working on the car.

x is amount of hours y is a cost of repair which depends on amount of hours for example: Car was repaird by 2 hours, so x=2 and cost of repair is y=50*2+20=120

The equation y = 50 x + 20 represents the total cost of car repairs, where 20 is a fixed fee and 50 is the hourly labor cost. It helps compute total expenses based on hours worked, improving transparency in the pricing process. This allows both the mechanic and customer to understand expected costs clearly.
