Answer: A.The cumulative customerminus−level operating income of the top eight customers represents about 105.1105.1% of operating income
Explanation:
The Cumulative total of the first 8 customers is,
= 5,563 + 4,474 + 3,851 + 1,049.5 + 984.80 + 844.80 + 336.60 + 252.00
= $17,355.70
The Cumulative total of the Operating Income is,
= 5,563 + 4,474 + 3,851 + 1,049.5 + 984.80 + 844.80 + 336.60 + 252.00 - 168 - 676
= $16,511.70
Dividing both figures gives,
= 17,355.70 / 16,511.70 * 100
= 1.0511051 * 100
= 105.1105.1%
Option A is therefore correct.
