Question

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.

a) Write and simplify a formula that can be used to predict the rice weevil population for any week after the beginning of the study.


b) Use the formula to predict the rice weevil population 10 weeks after the beginning of the study

Answer 1

A. 600w + 400 = r B. 6400

The 600 is how much each week the weevils grow. The W is for every additional week and the 400 is for the original amount of weevils.

600×10+400=6400
