A(t) = 107 ( 1.015)^t

The growth rate is 1.015-1 = .015 = 1.5%

B(t) = 88(1.025)^t

The growth rate is 1.025 -1 = .025 = 2.5%

B has a faster growth rate

The constant in front is the initial number of trees, A has 107, B has 88 so A has a greater number of trees initially

107-88 =19 tree

A has 19 more trees than B at the start

30 years

A(30) =107 ( 1.015)^30= 167.24958 = 167 trees

B(30) = 88(1.025)^30=184.58594 = 185 trees

Forest B has more trees after 30 years

Rounding to 2 decimal places

184.59 - 167.25 =17.34 trees
