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

Help plssssssssssssssssssss
Whitepunk [10]

Answer: -74

Step-by-step explanation:

First you have to solve - 2y - 9 = 7 to find what "y" equals so we can plug that into 9y - 2

1. Solve -2y - 9 =7:

-2y = 16

y = -8

2. Plug -8 into the expression 9y - 2:

9(-8) - 2

-72 -2

-74!

Im sorry if i didnt do this correctly :/
