Final answer:
You can do 2 days of skiing with $250.
Step-by-step explanation:
To find out how many days of skiing you can do with $250, you need to divide the total amount of money you have by the cost of skiing per day. In this case, skiing costs $100 per day. So, the calculation would be:
$250 ÷ $100 = 2.5
Since you can't do half a day of skiing, you can do 2 days of skiing with $250.
