Answer 1

Answer: Leia pays more to fly from the UK to Australia

Step-by-step explanation:

We have two persons, Andy and Leila; both travel from UK to Australia but in different ways:

For Andy:

-He first flies from UK to Japan and the cost of the ticket is $\£ 554$

-Then he flies from Japan to Australia and the cost of the ticket is $70140 Yen$

So, the cost of Andy's trip is:

$\£ 554+70140 Yen$ (1)

Taking into account that we have to use the same units to sum two quantities, we have to convert the Yens to $\£$; knowing that $\£ 1=140 Yen$:

$70140 Yen \frac{\£ 1}{140 Yen}=\£501$

Then, (1) is rewritten as:

$\£ 554+\£501=\£1055$ (2) This is the total cost of Andy's trip

For Leila:

She flies directly from UK to Australia and the cost of her ticket is $\ 1860$ (Australian dollars)

Taking into account that we have the price of Andy's trip in $\£$, we have to convert the Australian dollars to $\£$, in order to compare.

So, knowing that $\ 1=\£ 0.62$ we have:

$\ 1860 \frac{\£ 0.62}{\ 1}=\£1153.2$ (3) This is the total cost of Leila's trip

Hence, comparing (2) and (3) we can see that Leila paid more to fly from UK to Australia.
