Solution step 1
Determine the number of homes
number of residence =
331270 X (lb/day) X (capita/day/3.82 lb) X
residence / 2.7 cap
number of residence = 32,118
What's wrong with the answer?
The demolition load, broken concrete may not
be representative; calculate the number of
houses with the concrete.
Solution step 1
number of residence =
(331,270-233,550) X (lb/day) X
(capita/day/3.82 lb) X residence / 2.7 cap
number of residence =
9,475 vs. 32,118 with the broken concrete.
