On average during the summer, a 30,000 ft3 costs $7 per day to cool, while a 25,000 ft house costs $6.60 per day to cool. Which house costs less per cubic foot to cool?

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)

$450 i think. hope this ☺
