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:
<u>For Andy:</u>
-He first flies from UK to Japan and the cost of the ticket is
-Then he flies from Japan to Australia and the cost of the ticket is
So, the cost of Andy's trip is:
(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 :
Then, (1) is rewritten as:
(2) This is the total cost of Andy's trip
<u>For Leila:</u>
She flies directly from UK to Australia and the cost of her ticket is (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 we have:
(3) This is the total cost of Leila's trip
Hence, comparing (2) and (3) we can see that <u>Leila paid more to fly from UK to Australia.</u>
