Question 1102594
<font color="black" face="times" size="3">
144 people total
30 said they don't like eggs and don't like toast
144 - 30 = 114 people like one item or the other (or both)


Let x = amount of people who like both
83 like eggs
65 like toast
x like both
83+65-x = 114
148-x = 114
148-x-148 = 114-148
-x = -34
<font color=red>x = 34</font>


<font color=red>Answer: Choice A) 34 people like both eggs and toast</font>


Side Note: I'm using the idea
n(A or B) = n(A) + n(B) - n(A and B)
where
n(A or B) = number of people who like A or B
n(A and B) = number of people who like A and B
n(A) = number of people who like A
n(B) = number of people who like B
