Given:
The cost C (in dollars) to participate in a ski club is given by,

Where x is the number of ski trips we take.
To find:
The number of ski trips when a total cost of $315 and $485 is spent.

Substituting C = 485 in the given equation we get,

Thus,
If we spend a total cost of $315, we can take 3 ski trips.
If we spend a total cost of $485, we can take 5 ski trips.
Final answer:
• If we spend a total cost of $315, we can take 3 ski trips.
,
• If we spend a total cost of $485, we can take 5 ski trips.
