A calculator manufacturing organization can produce two models of calculator

at two different manufacturing facilities. It is observed that manufacturing facility

A can produce $140$ scientific calculators and $25$ graphing calculators each day.

Similarly, it is observed that manufacturing facility B can produce $60$ scientific

calculators and $90$ graphing calculators per day. It costs $$1200$ per day to

operate manufacturing facility A and $$900$ per day to operate manufacturing

facility B$.$ If the company needs to produce $460$ scientific calculators and $340$

graphing calculators for a big order, then determine the minimum cost incurred

in performing the production for this order. Present detailed steps followed in

solving this problem.
