Answer:
The correct answer is option (a).
Step-by-step explanation:
According to the scenario, the given data are as follows:
Sales of polyester = $2,553
Operating income = $73
So, Operating return on polyester = ( Operating income ÷ Sales of polyester ) × 100
= ($73 ÷ $2,553) × 100
= 2.86% or 2.9%
Now Sales of fiber = $3,452
Operating income = $690
So, Operating return on fiber = ( Operating income ÷ Sales of fiber ) × 100
= ($690 ÷ $3,452) × 100
= 19.99% or 20%
