Midwest 2019 = $1,025 / $6,475 = 15.83%

Midwest 2020 = $1,375 / $6,775 = 20.3%

Midwest 2021 = $1,325 / $6,975 = 19%

Southeast 2019 = $775 / $12,175 = 6.37%

Southeast 2020 = $975 / $12,775 = 7.63%

Southeast 2021 = $1,375 / $13,075 = 10.52%

asset turnover = net sales / average total assets

Southwest 2019 = $14,675 / $13,775 = 1.07

Midwest 2019 = $6,475 / $4,475 = 1.45

Midwest 2020 = $6,775 / $3,975 = 1.7

Midwest 2021 = $6,975 / $3,975 = 1.75

Southeast 2019 = $12,175 / $5,075 = 2.4

Southeast 2020 = $12,775 / $5,375 = 2.38

Southeast 2021 = $13,075 / $5,375 = 2.43

return on investment = net income / cost of investment
