Answer:
.4792 or 47.92%
Explanation:
The computation of the weight of C is shown below:
But before that first determine the following things
For A is
= 100 × $22
= $2200
For B
= 600 × $17
= $10200
For C
= 400 × $46
= $18400
For D
= 200 × $38
= $7600
So,
Total = 38400
And, finally
weight of C is
= $18,400 ÷ $38,400
= .4792 or 47.92%
