Answer:
Consumption ratios for the four drivers in relation to both the cards will be consumption for a particular card/total consumption for both the cards which will be as follows :-
Total consumption for Inspection = 140 + 60
= 200
Total consumption for Setup = 60 + 20
= 80
Total consumption for Machine = 180 + 650
= 830
Total consumption for Number of moves = 230 + 60
= 290
Hence,
Consumption ratios for Inspection hours:
Scented Cards =
= 0.7
Regular Cards =
= 0.3
Consumption ratios for Setup hours:
Scented Cards =
= 0.75
Regular Cards =
= 0.25
Consumption ratios for Machine hours:
Scented Cards =
= 0.22
Regular Cards =
= 0.78
Consumption ratios for Number of moves:
Scented Cards =
= 0.79
Regular Cards =
= 0.21
