#6. Allied Laboratories is combing some of its most common tests into one-price packages. One such package will contain three tests that have the following variable costs: Disposable Syringe Blood Vial Forms Reagents Sterile Bandages Breakage/losses Test A $4.00 $0.50 S0.15 $0.80 $0.20 $0.05 Test B $4.00 S0.50 $0.15 $0.60 S0.20 $0.05 Test C $4.00 S0.50 $0.15 $1.20 $0.20 $0.05 When the tests are combined, only one syringe, form, and sterile bandage will be used. Furthermore, only one charge for breakage losses will apply. However, you will need three blood vials and three individual reagents (pay attention to the price of the regents). Assuming marginal cost pricing, what is the cost of the combined test? Choice: $8.00 Choice: $4.50 Choice: $6.90 Choice: $8.50
