Answer:
Workers : Variable Inputs
Oven : Fixed Inputs
Step-by-step 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.
