You can put this solution on YOUR website!
THE COMBINED POPULATION OF BOTH THE CITIES IS GIVEN FOR YEAR 1995.
LET US ASSUME THAT THE POPULATION OF CITY ANCHORAGE IS x
THEN THE POPULATION OF CITY TAMPA BECOMES 25000-x
POPULATION INCREASE IN ANCHORAGE BY 1960

10% of x
POPULATION INCREASE IN TAMPA BY 1960

9% of (25000 - x)
TOTAL POPULATION INCREASE IS GIVEN BY
10x/100 + 9*(25000-x)/100 = 2380
(10x + 9*25000 - 9x)/100 = 2380
10x - 9x + 225000 = 2380*100
x + 225000 = 238000
x = 238000 - 225000
x = 13000
SO population of ANCHORAGE IN 1995 WAS 13000
AND population of TAMPA IN 1995 WAS 25000 - 13000 = 12000
