Suppose that you are hired by a local gardening association to monitor the populations of stink bugs in two different locations for one full year. Using the capture/recapture method, you collect the data shown in the table below.

Based on the information you have collected, which of the following is the growth rate for Population A?

Population A Population B
Starting number of stink bugs 1000 600
Number of new stink bugs hatched 200 60
Total number of stink bugs that die 40 200
