Question 1061155
at the beginning of 1990, the population was 30000.


it grew by 50/3% in that year.


50/3% = 50/3/100 = 50/300 = 5/30 = 1/6.


1/6 * 30000 = 5000


at the beginning of 1991, the population was 30000 + 5000 = 35000.


it grew by 10% in that year.


10% = 10/100 = 1/10.


1/10 * 35000 = 3500.


at the beginning of 1992, the population was 35000 + 3500 = 38500.


the beginning of 1991 is the same as the end of 1990.
the beginning of 1992 is the same as the end of 1991.
