HEY!!

THE ANSWER IS HERE,

Per capita INCOME of 4 FAMILIES is $15,000.

Income of 3 families are $10,000 ; $20,000 ; $12,000.

Per capita income= Total income / total population.

Let the income of 4TH family be x.Then

15,000=(10,000+20,000+ 12,000+x)/4

=>60,000 = 42,000+x

=> x =60,000-42,000.

=> x = $18,000.

so, the income of 4th family is $18,000.
