1. **State the problem:** We need to find an expression for the total cost to purchase and operate 6 snow fans. 2. **Identify given values:** - Cost to purchase one fan: 1200 - Daily operation cost per fan: 9.50 - Number of fans: 6 3. **Write the expression:** The total purchase cost for 6 fans is $6 \times 1200$. The total daily operation cost for 6 fans is $6 \times 9.50$. 4. **Combine the costs:** Total cost = Purchase cost + Operation cost $$\text{Total cost} = 6 \times 1200 + 6 \times 9.50$$ 5. **Simplify the expression:** $$= 7200 + 57$$ $$= 7257$$ 6. **Interpretation:** The total cost to purchase and operate 6 snow fans for one day is 7257. This expression helps the ski resort understand the combined cost of buying and running the fans daily.
