While on vacation in Europe you notice that a tablet computer is selling for 600 euros in France and for 533 pounds in Britain.
serg [7]

The cost of the tablet computer is less in France. It is $8.

Step-by-step explanation:

Cost in France = 600 euros

75 euros = 1 dollar

600 euros = 600/75 dollars

=$ 8

Cost in Britain = 533 pounds

65 pounds = 1 dollar

533 pounds = 533/65 dollars

= $8.2

The cost of the tablet computer is less in France. It is $8.
