Do you understand what the question is asking? In particular what are the definitions of "isoquant" and "isocost"?
iso ≈ the same
isoQUANT = a curve showing all combos of prof and admin staff that gives the same QUANTITY
isoCOST = a curve showing all combos of prof and admin staff that gives the same COST
The same quantity of what? Given the salaries of professors and staff, I can see how you would calculate "isocost" but what influence does one professor or one staff member have on "quantity"?
q = the amount of education, if you wish. they're not producing honey, but knowlegde.
