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 cereal in each box weighs 160g. The company wants to have a special offer 25% more cereal in each box do not change the price Here is Janes idea reduce the price and do not change the amount of cereal added in the box jane wants her idea to give the same value for money as tims idea. By what percentage does she need to reduce the price

20% reduction

Step-by-step explanation:

Given

Required

Price reduction in Jane's idea

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

Express 1 as percentage

So, the original idea is:

i.e. 200g costs 3 pounds each

Calculate unit price

pound per gram

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

pound

The percentage reduction is then calculated as:

26

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
