Answer: Percentage change =20 % decrease

Step-by-step explanation:

Given original price =£800

New price= £640

Now change in price = £800 - £640

= £160

Since the new value is less than the old value so the percentage change will be negative i.e. decrease in percentage

Percentage change =  (Change in Price/ Original Price)× 100

% change= (£160/£800)×100

=\frac{1}{5}\times 100

=20 %

Hence percentage change in price = 20% decrease

<span>There is a decrease of 20% from ÂŁ800 to ÂŁ640.

    A change from 800 to 640 represents a negative change (decrease) of -20% Using the formula :

   Percent change = [(800 - 640) / 800] x 100 = -20 % (decrease)

       800 is the old value and 640 is the new value. In this case we have a negative change (decrease) of -20 percent because the new value is smaller than the old value.</span>

tankabanditka [31]

Answer:

yes, the given relation is a function.

Step-by-step explanation:

The given relation is

{(–3, –2), (–1, 0), (1, 0), (5, –2)}

A relation is called function if each element of the domain is paired with exactly one element of the range.

It means for each value of x there exist a unique value of y.

In the given relation for each value of x there exist a unique value of y.

Therefore the required solution is yes and this relation is a function.
