The population of mastertown was 23,000 in 2012. assume that mastertown's population increases at a rate of 2% per year. write an equation to model the population of master town(y) based on number of years since 2012 (x)

23,000+.02x=y. You have to add 2% or .02 times the number of years(x) to 23,000 to get the populatin(y) from 2012

Rounding decimals is very similar to rounding other numbers. if the hundredths and thousandths places of a decimal is forty-nine or less, they are dropped and the tenths place does not change. for example, rounding 0.843 to the nearest tenth would give 0.8. , your welcome !
