In surveying families with pets, 5 out of 7 families owned a dog. if 35 families had dogs, how many families were surveyed?

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
