Hi guys,

I am a student studying Social Sciences Minor in Economic :P
I have this question here where I cannot understand I was wondering if anyone can help me step by step to solve it? Many thanks

Question:
Medical Testing Lab Inc. provides routine testing services for blood banks in the local area. Tests are supervised by skilled technicians using equipment produced by two leading competitors in the medical equipment industry. Records for the recent month show an average of 27 tests per hour being performed on the Testlogic-1 machine, and an average of 48 tests per hour on a new machine called the Accutest-3. On average, each machine is operated 200 hours per month. The Testlogic-1 is currently leased at $18000 per month, and the Accutest-3 is leased at $32000 per month.

a) On a per month basis, is Medical Testing Lab running an optimal mix of testing equipments? Explain.

b) Calculate the current marginal rate of technical substitution between the Testlogic-1 and the Accutest-3. If the marginal productivity of both equipments increases by 100%, will the marginal rate of technical substitution between two be affected? Why or why not?
