To determine the maximum number of tablets the teacher can buy, we need to divide the total amount of money the teacher has ($6,000) by the cost of each tablet ($250).
Step 1: Calculate the maximum number of tablets the teacher can buy:
$6,000 ÷ $250 = 24
The teacher can buy a maximum of 24 tablets for their classroom.
Please note that this calculation assumes that the teacher will spend the entire $6,000 on purchasing tablets and that there are no additional costs or discounts involved.
