When Anne Betty and Cynthia compared the amount of money each had, they discovered that Anne and Betty together had $12 Betty and Cynthia together had $18 and Anne and Cynthia together had $10.
<span>Who had the least amount of money? and how much was it?
a +b = 12
b + c = 18
a + c = 10
So what I did is simple XD A logical guess and check. I started with a = 1, but that was to little. And also didn't match up. So I kept going up and got a = 2, b = 10, and c = 8</span>

Answer:
it`s not true that for every person, if the person is happy, the person has a large income/there are people that are happy and doesn't have large incomes
Step-by-step explanation:
let be x the group of people in the world
let be I(X)=x has a large income
let be H(x)=x is happy
Having a large income is not a necessary condition for a person to be happy.
¬∀x, H(x)-->I(x)
<em>it`s not true that for every person, if the person is happy, the person has a large income</em>
∃x / H(x)^¬I(x)
<em>there are people that are happy and doesn't have large incomes</em>
If you round both numbers to the nearest thousand, you have 17,000 - 6,000 which is the best estimate.
