Practice objective / multiple choice question 39 from the 2024 Neco Agricultural Science examination.
A pest population on a crop starts at 120 insects per plant. In the absence of control it increases by 25 % each week. A pesticide applied once per week reduces the current population by 40 % instantly; each application costs \(\text{₦}500\) and at most one application can be made in a week.
