Trent had $20 to spend on 5 notebooks. After buying them, he had $7.50 left. If each notebook is the same price, how much did each notebook cost?

To determine how much each notebook cost, follow these steps:

1. **Calculate the total amount spent on notebooks:**
   \[
   \text{Total amount spent} = \text{Initial amount} - \text{Amount left}
   \]
   Trent initially had $20 and had $7.50 left after buying the notebooks:
   \[
   \text{Total amount spent} = 20 - 7.50 = 12.50
   \]

2. **Determine the cost of each notebook:**
   Since Trent bought 5 notebooks and spent $12.50, the cost per notebook is:
   \[
   \text{Cost per notebook} = \frac{\text{Total amount spent}}{\text{Number of notebooks}} = \frac{12.50}{5} = 2.50
   \]

Thus, each notebook cost $2.50.
