Is this how to do it correctly?

Mariah Enterprises makes a variety of consumer electronic products. Its camera manufacturing plant is considering choosing between two different processes, named Alpha and Beta, which can be used to make a component part. To make the correct decision, the managers would like to compare the labor and multifactor productivity of process Alpha with that of process Beta. The value of process output for Alpha and Beta is $170 per unit of product A and $180 per unit of product B, and the corresponding overhead costs for Alpha and Beta are $5,000 and $3,000, respectively. Process Beta Product Output (units) Labor ($) Materials ($) Process Alpha A B 40 70 $1,200 $1,400 $3,500 $1,400 A 60 $1,000 $3,000 B 30 $2,000 $1,500 a. Which process, Alpha or Beta, is more productive? Process Alpha has 43% higher labor productivity. Process Alpha has 4.16 % higher multifactor productivity. (Enter your responses rounded to the nearest whole number.) b. What conclusions can you draw from your analysis? The process that generates more dollars of output per dollar invested in input is Process Alpha . The process that exploits labor more efficiently is Process Alpha
