A polling company found that, of 300 households surveyed, 120 spent at least $100 per month on both gasoline and electricity, 60 spent at least $100 per month on gasoline but not on electricity, and for every household that did not spend at least $100 per month on gasoline or electricity, 4 spent at least $100 per month on electricity but not on gasoline. How many of the 300 households did not spend at least $100 per month on either gasoline or electricity?
Choose the correct choice from the following choices
A) 24
B) 30
C) 36
D) 90
E) 96
For every household that did not spend at least $100 per month on gasoline or electricity = P ,   4 spent at least $100 per month on electricity but not on gasoline = 4P   Spent = 300 - P   again spent = 60+120+4P   Now,   300 - P = 60+120+4P   or, 5P = 120   or, P = 24 (24nswer)
