1. The problem states that Eric rented a car for 5 days at a total cost of 180. 2. We need to find the cost to rent the car for 3 days at the same rate. 3. First, find the daily rental rate by dividing the total cost by the number of days: $$\text{Daily rate} = \frac{180}{5}$$ 4. Simplify the fraction: $$\text{Daily rate} = \frac{\cancel{180}}{\cancel{5}} = 36$$ 5. Now, multiply the daily rate by 3 days to find the total cost for 3 days: $$\text{Cost for 3 days} = 36 \times 3 = 108$$ 6. Therefore, it will cost Eric 108 to rent the car for 3 days at the same rate.
