Here is Jack's idea for the special offer.
Put 25% more cereal into each box and do not change the price.
Here is Sadia's idea
Reduce the price and do not change the amount of cereal in each box
Sadia wants her idea to give the same value for money as Jack's idea.
By what percentage does she need to reduce the price?

25%

Step-by-step explanation:

becouse she is reducing the price

the answer is 4.8 units on e2020.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
