The workstations cost $1,000 each and are made up of the following: Material Content 100 lbs of steel 90% postconsumer; 30 lbs of plastic 50% postconsumer; 5 lbs Other; What cost can the team attribute to recycled content for each workstation?
A: $770
B: $110
C: $660
D: $900

参考答案: A

本题解释:
Materials and Resources Credit Recycled Content, Calculations

To discover what part of materials cost can be attributed to the recycled material, the cost must be weighted.

Total weight is 135 lbs

100 lb steel X 90% post consumer = 90 lbs / 135 lbs = 66%
66% X $1,000 = $660

30 lbs plastic X 50% post consumer = 15 lbs / 135 lbs = 11%
11% X $1,000 = $110

Total cost of the recycled material is $770.00
