Janet's Performance Pizza is a small restaurant in Detroit that sells gluten-free pizzas. Janet's very tiny kitchen has barely enough room for the two ovens in which her workers bake the pizzas. Janet signed a lease obligating her to pay the rent for the two ovens for the next year. Because of this, and because Janet's kitchen cannot fit more than two ovens, Janet cannot change the number of ovens she uses in her production of pizzas in the short run.
However, Janet's decision regarding how many workers to use can vary from week to week because her workers tend to be students. Each Monday, Janet lets them know how many workers she needs for each day of the week. In the short run, these workers are inputs, and the ovens are inputs.

Workers : Variable Inputs

Oven : Fixed Inputs

Explanation:

Variable Inputs are the inputs which can be changed in short run. Short run is a period of time in which all the factors of a business can't be changed, some are fixed (constant) & some are variable (change-able)

Fixed Inputs are the inputs which cant be changed in short run, can only be changed in long run. Long run is a period in which firm can change all its inputs

In short run, Janne's pizza store can't change the number of ovens, but can change the number of workers. So, Workers are a variable input & Ovens are fixed inputs.
