Tim and Jane both work for a company that sells boxes of breakfast cereal. The boxes of cereal cost £3.00 and the amount of cere

Anna [14]

Answer:

20% reduction

Step-by-step explanation:

Given

$Price = 3.00$

$Weight = 160g$

$Rate = 25\%$

Required

Price reduction in Jane's idea

First, calculate the new weight of the box (the original plan)

$New = Weight * (1 + Rate)$

$New = 160g * (1 + 25\%)$

Express 1 as percentage

$New = 160g * (100\% + 25\%)$

$New = 160g * (125\%)$

$New = 200g$

So, the original idea is:

$200g \to #3.00$

i.e. 200g costs 3 pounds each

Calculate unit price

$Unit = \frac{3.00}{200}$

$Unit = 0.015$ pound per gram

For Jane's idea, the price of each box will be:

$Price = Weight *Unit$

$Price = 160 * 0.015$

$Price = 2.40$ pound

The percentage reduction is then calculated as:

$\% Reduction = \frac{Original\ Price -Janes\ Price}{Original\ Price} * 100\%$

$\% Reduction = \frac{3.00 - 2.40}{3.00} * 100\%$

$\% Reduction = \frac{0.6}{3.00} * 100\%$

$\% Reduction = \frac{60}{3.00}\%$

$\% Reduction = 20\%$
