An auto-repair shop faces the following weekly costs: rent. $600; labor, $500 per worker: parts and supplies, $60 per repair. Each worker can repair 3 cars per week. Fill in the costs in the table below. If the shop repairs 15 cars in a week, the total costs are $ ______. If the shop repairs 0 cars in a week, the total costs are $ ______.

Answer 1

To calculate the total costs of an auto-repair shop, you need to consider fixed costs (rent) and variable costs (labor and part supplies).

Step-by-step explanation:

To calculate the total costs, we need to consider the fixed costs (rent) and the variable costs (labor and part supplies).

Given that each worker can repair 3 cars per week, and that the labor cost is $500 per worker, we can calculate the labor cost as $500 multiplied by the number of workers. Assuming the shop employs 'w' workers, the labor cost would be $500 * 'w'.

The cost of parts and supplies per repair is given as $60 per repair, and since the shop repairs 15 cars in a week, the cost of parts and supplies would be $60 multiplied by 15, which equals $900.

Therefore, the total costs for the shop repairing 15 cars in a week can be calculated as follows: Total costs = Rent + Labor cost + Parts and supplies cost = $600 + ($500 * 'w') + $900.

If the shop repairs 0 cars in a week, the total costs would only include the fixed costs, which is equal to the rent, so the total costs would be $600.
