Answer:
The factor productivity of the firm is 3.16.
Explanation:
The total factor productivity can be calculated using the following formula:
Factor Productivity = Total Output ($) / Total Input ($)
Here input cost is labor cost $20, paint cost $30, supplies cost $10 and the energy cost $3 which are incurred to earn $199 (Output cost). So by putting the values in the equation, we have:
Factor Productivity = $199 / ($20+$30+$10+$3)
Factor Productivity = 3.16
