3. The city of Dakota Heights wants to determine where to locate postal substations so as to minimize the construction cost while servicing every postal zone. The city has been divided into twelve postal zones. Six possible locations for the substations have been identified. The cost of building at each location and the districts the location can service appear in the table below. LocationCost Zones that can be serviced

1. $52,000 1,2,3,11,12

2. $42,000 1,4,6,11

3. $47,000 2,4,5,8,10

4. $49,000 3,5,6,7,9

5. $38,000 4,6,7,8

Is this problem an Allocation, Covering, Blending, Product Portfolio, Production Planning, or Data Envelope Analysis problem? Explain your answer in a few short sentences

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

won't that be plagrisim thought?
