What is the total amount spent if 3 items are purchased at $12 each?

To determine the total amount spent when purchasing 3 items at a price of $12 each, you can use the formula for total cost, which is calculated by multiplying the number of items by the cost per item.

In this case, you would multiply 3 (the number of items) by $12 (the cost of each item):

Total amount spent = 3 items × $12/item = $36.

This calculation shows that the total expenditure for the items purchased is indeed $36, supporting the correctness of this answer.
