Question

The population of white pines on his land in 2015 was 40. After last weekend the population is 155. Find the growth rate.

Answer 1

287.5%

Step-by-step explanation:

Initial = 40

Recent = 155

Growth rate = ( recent - initial )÷ initial ×100/1

=( 155-40/40) × 100/1

= 115/40×100/1

= 2.875×100/1

= 287.5%

The rate of growth is 287.5%
