Answer: $24
Explanation:
Given that,
Two workers serve = 16 customers per hour
Three workers serve = 22 customers per hour
Each customer spends an average of $4 in the store.
Total revenue from Two workers = 16 × $4
                                                        = $64
Total revenue from Three workers = 22 × $4
                                                           = $88
Therefore, the marginal benefit of hiring the third worker would be:
=  Total revenue from Three workers - Total revenue from Two workers
= $88 - $64
= $24
 
        
             
        
        
        
Answer: variable; fixed
Explanation: In the short run, Kyoko's workers are variable inputs. This is because, the number of workers needed can be varied based on production needs, even in the short run. Examples are energy, labor etc. 
Kyoko's ovens are fixed inputs. Fixed inputs are those inputs whose quantities cannot be changed in the short run by a firm as it seeks to change the quantity of output produced. Examples are equipment, land and building.
