An asphalt concrete mix is purchased to resurface a parking lot. The sand for the cement is extracted 220 miles away, the concrete is from 750 miles away, and the aggregate is from 625 miles away. The total cost for the concrete will be $265,000. Concrete will make up 15%, sand 35% and aggregate 50%. What is the allowable cost for Materials and Resources Credit, Regional Materials?
A: $92,750
B: $0
C: $265,000
D: $132,500

参考答案: A

本题解释:
Reference: Materials and Resources Credit, Regional Materials

Weigh the percentage of the qualifying material for the allowable cost.

Sand is the only part of the concrete that meets the requirements for regional material, within 500 miles.

The sand is 35% of the total mix. $265,000 X 35% = $92,750
