The total cost of the ski hat and the ski boots is $112.35.
Step-by-step explanation:
First, we need to add the prices of the ski hat and the ski boots.
85.50 + 19.50 = $105
Now, we need to find 7% of $105, and then add it to the total.

105 + 7.35 = $112.35
Therefore, the total cost of the ski hat and the ski boots is $112.35.
