a) you need to convert one of the prices so both of them are in the same units and you can compare them.
im going to convert the Japanese Yen into Euros as the numbers will be smaller but you can also do it the other way.
£1 = 188 japanese yen
?? = 39856 japanese yen
divide 39856 by 188 to get £212
this means 39856 Japanese Yen is equal to £212
then convert this into euros.
£1 = €1.41
£212 = ???
calculate 212 × 1.41 which gives you €298.92
this means 39856 Japanese Yen is equal to €298.92
the phone in Spain costs €352.50
this shows that the phone in Spain is more expensive than the one in Japan.
therefore, the mobile phone in Japan is cheaper.
b) from Part A, we know that the phone in Japan is 39856 Japanese Yen, which is equal to £212.
so now we need to convert €352.50 into Pounds (£) to compare the prices.
£1 = €1.41
?? = €352.50
divide 352.50 by 1.41 to get £250.
this means the phone in Spain costs £250 as €352.50 is equal to £250.
now we know the phone in Japan is £212 (in pounds) whereas the phone in Spain is £250 (in pounds).
we need to calculate the difference by doing £250 - £212 which equals £38
therefore, the phone in Japan is cheaper than the phone in Spain by £38
