Case 1: Tom Stays in Walterboro
Tom will pay $30 plus tax for the hotel room. At the standard 7% tax, this makes his extra costs (above his usual cost of driving to Walterboro and home) a total of: $32.10
Case 2: Tom Goes Home for the Night and Returns to Walterboro the Next Day
We have to figure out how much extra he will pay in gas. Going hom will add an extra trip to Statesboro and an extra trip back to Walterboro. With gas at $1.25/gallon, his truck getting 31 miles/gallon and the distance being 125.9miles between Statesboro and Walterboro, we find that Tom spends:
$10.15 extra by spending the night at his apartment in Statesboro.
Therefore,
he will be saving money returning to his apartment for the night
and driving back to Walterboro the next day.
