4 identical pens cost 252 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 4x=252. Dividing by 4, x=63. 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: 4x = 252, x = 63.
