Answer:

[tex]Total = 3E + 2N + S[/tex]

Step-by-step explanation:

Efficiency with E; Noise Level with N

and Service and Installations with S

Required

Determine the correct formula

From the question

3 points goes to E: i.e. 3E

2 points goes to N: i.e. 2N

The above is the number of points more than service and installations.

So 1 point will be given to S i.e. S

The total or formula is:

[tex]Total = 3E + 2N + S[/tex]
