Answer: Grace paid $1.40 per notebook and Jamal paid $1.10 per notebook.
Explanation:
Hi to solve this problem we have to analyze the information given:
- Grace : 2 notebooks for $2.80
- Jamal: 4 notebooks for $4.40
To calculate the unit price of each student's notebooks we have to divide the total price that each one paid by the number of notebooks that each one bought.
So, mathematically speaking:
- Grace : $2.80 / 2 = $1.40 per unit.
- Jamal : $4.40 / 4 = $1.10 per unit
In conclusion, Grace paid $1.40 per notebook and Jamal paid $1.10 per notebook.
