Michael has a chicken farm. His chickens increase in number by 150 chickens annually. If the number of chickens on his farm now is 550, how many will he have after 9 years?

How many chickens will Michael have after 9 years? ** The number of the increase in chicken after 9 years is 150 * 9 = <<150*9=1350>>1350.
How many chickens will Michael have after 9 years? ** So the total number of the chicken in Michael's farm will be 550 + 1350 = <<550+1350=1900>>1900.
#### 1900
