1. **State the problem:** We are given the linear equation $$y = 0.37x + 5$$ which models the toll cost $$y$$ based on miles driven $$x$$. 2. **Identify what is asked:** Find the toll cost for driving 70 miles. 3. **Use the formula:** Substitute $$x = 70$$ into the equation: $$y = 0.37 \times 70 + 5$$ 4. **Calculate the multiplication:** $$y = 25.9 + 5$$ 5. **Add the constants:** $$y = 30.9$$ 6. **Interpret the result:** The toll cost for 70 miles is exactly 30.9 (units of currency). **Note:** The user mentioned it would cost 25, but according to the formula, the exact cost is 30.9. **Final answer:** $$\boxed{30.9}$$
