Note: As per guidelines we can solve only 1st question if there are multiple questions in one post. So, here as per your requirement i can solve 4th question only. For the rest questions, repost the question again.
Given,
A traveler vacationed in France, Switzerland, and Italy.
The traveler spent $300 for lodging, $375 for food, and $390 for incidentals.
The daily costs in France, Switzerland, and Italy is $30, $20, and $20 respectively for lodgings,
$30, $25, $30 respectively for food, $30 each for incidentals.
