Answer:
The correct answer is 0.67.
Step-by-step explanation:
According to the given scenario, the given data are as follows:
Number of cars per hour ( output) = 12 cars
Number of employees ( input ) = 2
Employees payment per hour (input) = $7.50
items using i.e water and soap ( input ) = $1 + $2
So, we can calculate multifactor productivity by using following formula :
Multifactor productivity = output / input
= 12 / ( 7.50 × 2 ) + $1 +$2
= 12 / 18
= 0.67
Hence, the correct answer is 0.67.
