Answer:
Workers are variable input and ovens are fixed input
Step-by-step explanation:
Inputs that can't be changed in short run are fixed inputs, as well as costs of acquiring them. These inputs stay the same in quantity and cost, no matter how many outputs are created. On the other hand, those inputs that can be changed in the short run are variable inputs, as well as expenses of acquiring them. They change in the short run with the changes in produced output.
