Stewart uses the formulas below to estimate the population of koalas in a habitat over four years.
`text{Population (Year 1)} = 5000`
`text{Population (Year 2)} = text(Year 1) + text(Year 1)/10`
`text{Population (Year 3)} = text(Year 2) + text(Year 2)/10`
`text{Population (Year 4)} = text(Year 3) + text(Year 3)/10`
What is the estimated population of koalas in year 4?
