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:

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:

Hence,
The coat is cheaper in London and it is 6.6 euros cheaper than in Dublin
Answer:
1. Western erodes 2 ft/yr; Dunes builds up at 5 ft/yr
2. Sometime in 2006
3. Solve simultaneous equations
Step-by-step explanation:
1. Erosion patterns
(a) Western Beach
In 15 yr, Western Beach erodes from 100 ft to 70 ft.
The rate of erosion is 30 ft/15 yr = 2 ft/yr.
(b) Dunes Beach
In 15 yr, Dunes Beach builds up from 20 ft to 95 ft.
The rate of buildup is 75 ft/15 yr = 5 ft/yr.
2. Beaches with equal width
From the table, it appears that the beaches will have the same width sometime in year 11 (2006).
3. Best approximation
The graph below also shows that it happens part way through year 11 (2006).
We could get an even better solution by calculating the equations of the two lines and solving the simultaneous equations.
The equation f(x) = 3x represents this relationship.
The answer is 27 because not only does it refer to the number line sequence it doesn't actually mean a big number comes behind it. what ever it starts with,it multiplies the same pass the big number
