A coat in London costs £60. The same coat in Dublin costs €105.60. The exchange rate is £1 = €1.65. In which city is the coat ch
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
