Assume that cost is 2 times more important than reputation and reputation is 3 times more important than compatibility with exis
dusya [7]
Let the weightage of Ease of Use be x
Ease of Use = x

<span>Compatibility is 5 times more than ease of use:
</span>Compatibility = 5x

<span>Reputation is 3 times more important than compatibility:
</span>Reputation = 3(5x)
Reputation = 15x

<span>Cost is 2 times more important than reputation:
</span>Cost = 2(15x)
Cost = 30x

So the weightage are:
Ease of Use : 1
Compatibility : 5
Reputation :15
Cost : 30

What do you want to find out? &gt; The rate at which Bill puts shringles on a rood. What do you know? &gt; Bill and Chip each fi
denis23 [38]

Answer:

  (a) b = (4/7)c

  (b) Bill: 40 shingles/hour; Chip: 70 shingles/hour

Step-by-step explanation:

Let b and c represent Bill's and Chip's rates in shingles per hour, respectively. Then we have ...

  7b = 4c

  c - b = 30 . . . . shingles per hour difference in rates

(a) Bill's rate in terms of Chip's rate can be found by dividing the first equation by 7

  b = (4/7)c . . . . . Bill's rate is 4/7 of Chip's rate

__

(b) To find the rates, we can multiply the second equation by 7 and substitute using the first equation:

  7c -7b = 210

  7c -4c = 210

  c = 210/3 = 70

  b = (4/7)(70) = 40

Bill's rate is 40 shingles per hour; Chip's rate is 70 shingles per hour.
