x2 - 22x + 121

= x2 - 11x - 11x +121

= x(x-11) - 11 ( x -11)

= (x-11) (x-11)

Answer:

Part a) In Geneva the watch is cheaper

Part b) The watch in Geneva is $\£20$ cheaper than the same watch in Manchester

Step-by-step explanation:

<u><em>The question is</em></u>

a) In which city is the watch cheaper?

b) By how much is it cheaper (in £)?

Part a)

Transform $CHF\ to\ \£$ in order to work with the same currency and make the comparison

If $\£1=1.55CHF$

$193.75\ CHF=193.75(\frac{1}{1.55})=\£125$

Now we can make the comparisons:

In Geneva the watch costs

$\£125$

and

in Manchester it costs

$\£145$

$\£125 < \£145$

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

$\£145-\£125=\£20$

Therefore

The watch in Geneva is $\£20$ cheaper than the same watch in Manchester
