Barton's Taco Tico

1. The wages paid to the taco makers and other employees are variable costs.

2. The cost of materials are also variable costs.

Explanation:

Variable costs vary in total but remain fixed per unit.  For example, the wages paid to the workers have a fixed rate.  Therefore, the total will vary, depending on the total hours worked by each worker.  Similarly, the costs of materials vary in total, but the price per material may be relatively fixed.
