Kamila buys a dress for £30 in a sale. It was advertised "25%off". Kamila says"25% of £30 is £7.50 so i saved £7.50". Explain wh

sveta [45]

Answer:

She was wrong in her analysis because the sales discount of 25% is the discount on the original cost of the dress and not the purchasing cost of the dress as explained below:

Step-by-step explanation:

From the question:

Purchasing cost price of the dress = £30

However, this cost (£30) was after a 25% Sales Discount

It, therefore, implies that £30 is equal to 75% of the cost price

75% of the original cost price = £30

100% of the original cost price = (30 x100%)/75%

Original cost price = £40

Therefore the 25% discount / savings on the cost

= £ (40-30)

= £10

She saved £10 by buying the dress at £30 instead of the original cost of £40

Negative four over five s equals 2

Olegator [25]

Hey there!

Negative 4 over 5 s: $-\frac{4}{5}s$

equals 2: $= 2$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First: Multiply both of your sides by $\frac{5}{-4}$

Like: $\frac{5}{-4} ( \frac{-4}{5})s \\ \\ \\ = \frac{5}{-4} (2)$

Cancel out $\frac{5}{-4} ( \frac{-4}{5} s)$

Keep: $\frac{5}{-4} (2)$ because this will give you the outcome!

$Answer: s = \frac{-5}{2}$

Good luck on your assignment and enjoy day!
