If the price of one pen is (p) rupees, what will be the price of (5) pens?
Answer and explanation
Correct answer: \(5p\)
The price of one pen is \(p\) rupees. Therefore, the total price of 5 pens is \(5\times p=5p\) rupees. \(p+5\) represents adding 5 rupees to the price, whereas here the price per pen must be multiplied by 5. Exam tip: Total cost of identical items = cost per item × number of items.
