Charlie's Chicken & Lentil restaurant operates in several countries, with each outlet having exactly the same items on the menu. Company policy is to charge the same basic price, measured in Bolandian
dollars, for any item in any country, but this basic price is supplemented by any local taxes.
In Bolandia the only tax is a general 25% tax on all restaurant food and drink, and in Charlie's a
customer pays $5.00 for a chicken burger with fries, and $2.00 for a soft drink. In Colandia the currenc
is the colan, and there are exactly two colans for every Bolandian dollar. There is no general tax on
restaurant food, but there is a special 50% tax on all soft drinks.
What would a customer in Colandia have to pay for a meal of a chicken burger with fries and a soft
drink at Charlie's?
