following items have been maintained during the renovation:

Item Size(sf) ; Reused Area(sf) ;%Reused
Foundation ;14,350 ; 14,350 ; 100%
Exterior Walls ; 54,063 43,250 ; 80%
(excluding windows);

本题解释:
Notes:
Only the Foundation, Exterior Walls, and Interior Structural Walls can count to MR Credit
1.1. So the calculation that looks like this:
Reused foundation = 14,350 SF
Exterior Walls = 43,250 SF
Interior Structural Walls = 430 SF
14,350SF + 43,250SF + 430SF = 58,030 SF
58,030SF is then divided into the total amount of material that could have qualified
14,350 + 54,063SF + 767 = 69,180 SF
58,030/69,180 = .838, round up, 84% is the answer
