<span>Profit needs to be maximized.
Profit = 30x+45y where x and y are respectively the number of model A and model B fax machines manufactured.
Objective function:
max(30x+45y)
Constraints:
x≥0 ---------------(1)
y≥0 ---------------(2)
x+y ≤ 2500 since the demand is capped at 2500 -----------(3)
100x+150y≤600000 since manufacturing costs cannot exceed $600000-----(4)
Solve the following two equations to identify where the two boundary lines (3) and (4) intersect.
x+y=2500-----(3)
100x+150y=600000---(4)
Multiplying (3) by 100
100x+100y=250000----(5)
(5)-(4)
50y=350000
y=7000
x=-4500
since the constraint states that x≥0, only three vertices are considered viz (0,0), (0,2500),(2500,0).
applying the profit function at each of the three vertices:
(0,0) ----- 30(0)+45(0) = 0
(0,2500) ---- 30(0)+45(2500)=112500
(2500,0) ---- 30(2500)+45(0)=75000
Hence by applying the max function, x=0, y=2500.
i.e. Dont produce any 'a' model machine. Manufacture 2500 units of model 'b' to maximise profit</span>
A customer service means an after sales service which gives an additional value to the product which consumers have bought. A good customer service must satisfy every costumer's expectation for the product they have bought. Example: After buying a smartphone, a consumer experience a minor failure. This smartphone customer service able to resolve this problem.
D a buyer could use the good or service on its own
Answer: Federal (national)
Explanation:
In the united state, the dual banking system is one of the type of banking system which include both the national and the state banks.
In the dual banking system, the national banks are basically regulated or controlled by the federal law and regulation and then also supervised by the federal agency.
The importance of this dual banking system is that it is necessary for maintaining the balance between the state and the national banks and also providing the various types of benefits to the system.
Therefore, Federal or the national banks is the correct answer.
