Neco 2020 Agricultural Science Question 43
Practice objective / multiple choice question 43 from the 2020 Neco Agricultural Science examination.
A cassava field shows leaf‑spot symptoms on \(12\%\) of the plants. A control measure reduces the disease spread so that each infected plant produces a total of \(1.5\) infected plants (the original plus \(0.5\) new) each week. Assuming the spread follows this discrete multiplication each week, after how many whole weeks will at least \(50\%\) of the field be infected? Give the smallest integer number of weeks.
