If a homeowner is trying to reduce the insect population in the yard and needs to decide between setting up an insect zapper. Introducing dragonflies would be more effective in reducing the insect population in the yard resulting in the fewest insects at the party.
Which one is more effective?
To find which method will result in the fewest insects at the party compare the effectiveness of the insect zapper and introducing dragonflies over a period of 4 days.
Method 1:
Insect Zapper
Let's assume there are initially 100 insects in the yard.
Day 1: 100 insects
(15% of 100 insects) = 85 insects remaining
Day 2: 85 insects
(15% of 85 insects) = 72 insects remaining
Day 3: 72 insects
(15% of 72 insects) = 61 insects remaining
Day 4: 61 insects
(15% of 61 insects) = 52 insects remaining
Method 2:
Introducing Dragonflies
Let's assume there are initially 100 insects in the yard.
Day 1: 100 insects - 100 insects (eaten by dragonflies) = 0 insects remaining
Day 2: 0 insects
100 insects (eaten by dragonflies) = 0 insects remaining
Day 3: 0 insects
100 insects (eaten by dragonflies) = 0 insects remaining
Day 4: 0 insects
100 insects (eaten by dragonflies) = 0 insects remaining
Comparing the results:
- Using the insect zapper there would be 52 insects remaining after 4 days.
- Introducing dragonflies would result in 0 insects remaining after 4 days.
Therefore introducing dragonflies would be more effective in reducing the insect population in the yard resulting in the fewest insects at the party.
