5A herpetologist is tracking the population of a rare frog species in a Bornean rainforest. She observes that the number of frogs in a pond triples every month due to ideal breeding conditions, but 40 frogs are lost each month due to predation. If the pond initially contains 50 frogs, how many frogs will remain after 4 months? - Decision Point

Amid growing global interest in biodiversity conservation, the daily monitoring of rare frog populations has become an important indicator of rainforest health. In the Bornean rainforest, a team of 5A herpetologist is closely observing a hidden ecosystem where these rare frogs thrive—vibrant, sensitive, and vital to ecological balance. With breeding cycles that propel population growth and natural pressures threatening stability, tracking their numbers reveals deeper stories about resilience and environmental interaction. This quiet but significant species captures attention from scientists, conservationists, and nature enthusiasts alike—especially as global trends spotlight the urgent need for species monitoring in vulnerable habitats.
Why is this research gaining traction in the US and beyond? The surge in public concern over amphibian declines, linked to climate change and habitat loss, fuels demand for clear, data-driven insights. This particular case—where initial numbers multiply rapidly but declines offset gains—serves as a real-world window into population dynamics. The monthly triple growth rate contrasts sharply with steady monthly losses, creating a natural puzzle: Will reproduction outpace predation, or will survival remain uncertain? For both researchers and concerned citizens, the count after four months offers tangible evidence of how fragile yet dynamic rainforest ecosystems can be.
Understanding the Context
Let’s explore the math behind this ecological story. Using the data provided—starting with 50 frogs, a monthly growth factor of 3, and a fixed loss of 40 frogs each month—here’s what unfolds over four months.
Month 1: Growth Outpaces Loss
Start: 50 frogs
Growth: 50 × 3 = 150 frogs
Subtract predation: 150 – 40 = 110 frogs remaining
Month 2: Acceleration Continues
Start: 110 frogs
Growth: 110 × 3 = 330 frogs
Subtract predation: 330 – 40 = 290 frogs
**Month 3: Population Reaches a Turning
