graces notebooks were $1.40 each  and Jamals were $1.10 each

Answer: Grace paid $1.40 per notebook and Jamal paid $1.10 per notebook.

Step-by-step 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.
