Answer:

Part a) In Geneva the watch is cheaper

Part b) The watch in Geneva is [tex]\£20[/tex] cheaper than the same watch in Manchester

Step-by-step explanation:

The question is

a) In which city is the watch cheaper?

b) By how much is it cheaper (in £)?

Part a)

Transform [tex]CHF\ to\ \£[/tex] in order to work with the same currency and make the comparison

If [tex]\£1=1.55CHF[/tex]

[tex]193.75\ CHF=193.75(\frac{1}{1.55})=\£125[/tex]

Now we can make the comparisons:

In Geneva the watch costs

[tex]\£125[/tex]

and

in Manchester it costs

[tex]\£145[/tex]

[tex]\£125 < \£145[/tex]

therefore

In Geneva the watch is cheaper

Part b)

If we want to know by how much is cheaper, subtract from the expensive price the value of the cheaper price

[tex]\£145-\£125=\£20[/tex]

Therefore

The watch in Geneva is [tex]\£20[/tex] cheaper than the same watch in Manchester
