5John is developing a sustainable packaging solution that reduces material usage by 15% each iteration. If the initial design uses 400 kg of material, how much will the fourth iteration use, assuming the reduction applies to the previous versions final amount?

**How Sustainable Packaging Shrinks Material Use—and What That Means for the Future** In an era where waste reduction drives innovation, a quiet revolution is unfolding in packaging technology. Consumer demand for eco-conscious solutions is rising, and companies are responding with bold approaches—like 5John’s iterative model that cuts material use by 15% with each new version. What starts as 400 kg of raw material doesn’t just shrink once—it compresses progress through repeated refinement. This staggered approach reflects a growing trend: smarter design based on measurable environmental impact, not just cost savings. Why is 5John’s method gaining traction now? Sustainability isn’t just a buzzword—it’s a core expectation. With packaging waste contributing significantly to global pollution, businesses are under pressure to deliver measurable reductions in resource use. Dynamic material optimization, where each iteration builds on the last, offers a scalable path forward. For US consumers and industry leaders alike, this approach aligns with both ethical values and practical efficiency. **Using the Math Behind the Reduction**
