Answer:
B. $0.50
Step-by-step explanation:
Assuming Printer C runs 60 hours (not 6) in Week 3, the equations for the number of cards per hour produced by each of the printers are ...
- 40a +50b +45c = 7950
- 45a +50b +40c = 7800
- 55a +30b +60c = 9600
The solutions to these equations can be found by various means. A graphing calculator (or any of several web sites) can solve the matrix equation to tell you the card production rates (in cards per hour) of each of the printers are ...
- a = 60
- b = 30
- c = 90
So the question about ink cost can be answered for printer B:
... ($15/hour)/(30 cards/hour) = (15/30) $/card = $0.50/card
