Step-by-step explanation:
Given:
[tex]\pounds1=1.55 CHF[/tex]
Multiply [tex]\pounds 145[/tex] by 1.55 to represent 145 pounds in Swiss Frances currency.
[tex]145 \times 1.55 = 224.75[/tex]
Compare:
[tex]193.75 < 224.75[/tex]
The watch in Geneva is cheaper.
How Much?
Divide 193.75 CHF by 1.55
[tex]193.75 \div 1.55 = 125[/tex]
Subtract:
145 - 125 = 20.
The watch is 20 Pounds cheaper.
