y=(3/2)^x
You probably mean well, but some of your answers, like the one above, are incorrect.
Make sure you are familiar with the topic before you answer.
decrease of 1.5% ---> 98.5% or .985
Population = 4500(.985)^t, where t is the number of years
so when t = 25
population = 4500(.985)^25
= 3084
to the nearest whole number, can't have partial people
