1. The problem states that Boone County has 858 to spend on new street signs, and each sign costs 26. 2. We need to find how many signs the county can buy with 858. 3. To find this, divide the total money by the cost per sign: $$\frac{858}{26}$$ 4. Calculate the division: $$\frac{858}{26} = 33$$ 5. Since the county cannot buy a fraction of a sign, they can buy 33 signs. **Final answer:** Boone County can buy 33 new street signs.
