Answer: There were 741 books in the library a year later.

Step-by-step explanation:

Given: Total books in library = 570

Pie

Answer:

The coat is cheaper in London and it is 6.6 euros cheaper than in Dublin

Step-by-step explanation:

Given

Cost of coat in London = £60

Cost of coat in Dublin = €105.60

In order to find where the coat is cheaper, the price should be in same unit

It is also given that

£1 = €1.65

so,

Price of coat in Euro will be:

$P = 60 * 1.65 = 99$

So the price of coat in London is 99 Euros

Comparing both the prices we see that

Price in London < Price in Dublin

99 < 105.60

The difference in price is:

$=105.60-99= 6.6\ Euros$

Hence,

The coat is cheaper in London and it is 6.6 euros cheaper than in Dublin
