Step-by-step explanation:

1.55 CHF = ?1

Cost of watch in Geneva in?1

1.55 CHF = ?1

193 CHF = ??1 which we could call x

1.55 = 1

193 = x

Cross multiply

1.55x = 193 Divide by 1.55

x = 124.52 in x units.

But the merchants in Manchester are charging 143 x units

So 143 - 124.52 = 18.48 units more expensive in Manchester.
