PERCENT OF CHANGE

This investigation explores the percentage change in price of various items from the 1970s to the present, focusing on food and cars. The research highlights significant price changes, noting that watermelons experienced the greatest increase due to their growing value, while milk showed the smallest change since it has remained a staple product. Additionally, predictions about future prices, such as for gumballs, illustrate ongoing trends in inflation. This analysis informs my understanding of pricing dynamics in today’s retail environment.

  7. Percent of change (Work)

  8. Conclusion 1.What item had the greatest percent change?  Why do you think this is the case? The watermelons had the greatest percent of change. I also think it’s because watermelons are now more valuable than before 2.What item had the smallest percent change?  Why do you think this is the case? Milk had the smallest percent change. Milk was probably not that valuable even now. Milk should not be expensive. 3.If a gumball costs 25 cents now, predict the price of a gumball in 30 years.  Can you imagine paying that much? I can predict that the price of a gumball will be atleast 2-3 dollars. As the years past the more prices rise up. 4.What impact does this research have on your future? This will impact the way I think about prices in malls or stores. I can just imagine how much all the things we have now would have cost back in the 1970s.
