Answer:
20% reduction
Step-by-step explanation:
Given
![Price = 3.00](https://tex.z-dn.net/?f=Price%20%3D%203.00)
![Weight = 160g](https://tex.z-dn.net/?f=Weight%20%3D%20160g)
![Rate = 25\%](https://tex.z-dn.net/?f=Rate%20%3D%2025%5C%25)
Required
Price reduction in Jane's idea
First, calculate the new weight of the box (the original plan)
![New = Weight * (1 + Rate)](https://tex.z-dn.net/?f=New%20%3D%20Weight%20%2A%20%281%20%2B%20Rate%29)
![New = 160g * (1 + 25\%)](https://tex.z-dn.net/?f=New%20%3D%20160g%20%2A%20%281%20%2B%2025%5C%25%29)
Express 1 as percentage
![New = 160g * (100\% + 25\%)](https://tex.z-dn.net/?f=New%20%3D%20160g%20%2A%20%28100%5C%25%20%2B%2025%5C%25%29)
![New = 160g * (125\%)](https://tex.z-dn.net/?f=New%20%3D%20160g%20%2A%20%28125%5C%25%29)
![New = 200g](https://tex.z-dn.net/?f=New%20%3D%20200g)
So, the original idea is:
![200g \to #3.00](https://tex.z-dn.net/?f=200g%20%5Cto%20%233.00)
i.e. 200g costs 3 pounds each
Calculate unit price
![Unit = \frac{3.00}{200}](https://tex.z-dn.net/?f=Unit%20%3D%20%5Cfrac%7B3.00%7D%7B200%7D)
pound per gram
For Jane's idea, the price of each box will be:
![Price = Weight *Unit](https://tex.z-dn.net/?f=Price%20%3D%20Weight%20%2AUnit)
![Price = 160 * 0.015](https://tex.z-dn.net/?f=Price%20%3D%20160%20%2A%200.015)
pound
The percentage reduction is then calculated as:
![\% Reduction = \frac{Original\ Price -Janes\ Price}{Original\ Price} * 100\%](https://tex.z-dn.net/?f=%5C%25%20Reduction%20%3D%20%5Cfrac%7BOriginal%5C%20Price%20-Janes%5C%20Price%7D%7BOriginal%5C%20Price%7D%20%2A%20100%5C%25)
![\% Reduction = \frac{3.00 - 2.40}{3.00} * 100\%](https://tex.z-dn.net/?f=%5C%25%20Reduction%20%3D%20%5Cfrac%7B3.00%20-%202.40%7D%7B3.00%7D%20%2A%20100%5C%25)
![\% Reduction = \frac{0.6}{3.00} * 100\%](https://tex.z-dn.net/?f=%5C%25%20Reduction%20%3D%20%5Cfrac%7B0.6%7D%7B3.00%7D%20%2A%20100%5C%25)
![\% Reduction = \frac{60}{3.00}\%](https://tex.z-dn.net/?f=%5C%25%20Reduction%20%3D%20%5Cfrac%7B60%7D%7B3.00%7D%5C%25)
![\% Reduction = 20\%](https://tex.z-dn.net/?f=%5C%25%20Reduction%20%3D%2020%5C%25)
Answer:
3+2 = 6-1
=> 5 = 5
5+3 = 9-1
=> 8 = 8
4+2=9-3
=> 6 = 6
3+2 = 9-4
=> 5 = 5
