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?
The number of the increase in chicken after 9 years is 150 * 9 =

So the total number of the chicken in Michael's farm will be 550 + 1350 = 
<gadget id="calculator">550+1350</gadget>
<output>1_900</output>
