Answer 1

The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.

The cost of cooling 25000 cubic foot house= $6.50

Cost per cubic foot=6.50/25000

= $0.00026

The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.
