Question

1. There are 400 rice weevils at the beginning of an insect study. The population is expected to grow at a rate of 150% each week.

Answer 1

You would take 400×1.5 since 150% as a decimal is 1.5 therefore your answer would be 600 rice weevils.

Answer 2

Answer with explanation:

Initial Population of Rice weevil in an Insect Study = 400

Rate at which population  of Rice weevil is growing =150 %

⇒Growth formula is Given by

  $=I_{0}\times [1+\frac{R}{100}]^n\\\\ \text{where }I_{0}=\text{Initial Population}$

R=Rate Constant

n=Duration or time Period

⇒Population After a week is given by,if we take a week as,n=1.

         $=400\times [1+\frac{150}{100}]^1\\\\=400 \times 1.5\\\\=600$
