> Their numbers for 2018 are spending $1 to earn $1.05. Of course, they also spent $0.80 to tell people about it and another $0.30 in R&D to develop new businesses which puts them firmly in the red. So their numbers for 2018 aren't spending $1 to make $0.50, they're spending $1 + $0.30 + $.80 = $2.10 to make $1.05, which is, I believe: $1.00 to make $0.50.
