The materials cost for a retail project will be $337,500. The project team specified several recycled-content materials. What percentage of the overall materials cost of the project can the recycled content apply to?

Cost Material Content
$ 65,000; Structural Steel ; 5% Post-consumer Recycled, 90% Pre-Consumer;
$ 7,400 ; Particle Board ; 95% Pre-consumer;
$ 22,000 ; Carpet ; 25% Post-consumer, 75%Pre-consumer;


A: 12%
B: 26%
C: 15%
D: 7%

参考答案: C

本题解释:
For this calculation remember that post-consumer recycled material counts for the full percentage while pre-consumer recycled material only counts for 1/2 the pre-consumer percentage of content.

($65,000 X 5%) + (65,000 X 90% X 0.5) = 3,250 + 29,250 = $32,500

$7,400 X 95% X 0.5 = $3,515

($22,000 X 25%) + ($22,000 X 75% X 0.5) = $13,750

$32,500 + $3,515 + $13,750 = $49,765

$49,765 / $337,500 = 15%
