3 identical pens cost 132 taka. If one pen costs x taka, which equation and value are correct?
Note
Let x represent the cost of one pen. Total cost = number of pens × price per pen, so 3x=132. Dividing by 3, x=44. Because all pens are identical, total cost equals number of pens multiplied by the cost of one pen. That gives the correct equation and value: 3x = 132, x = 44.
