Question

There are m number of pencil boxes of 10 dollars each and n number of pen boxes of 12 dollars each. Which of the following represents the total price of the pen and pencil boxes?

• A. (10m + 12n) dollars
• B. (12m + 10n) dollars
• C. 22mn dollars
• D. 22m dollars

Answer 1

The correct option is A (10m + 12n) dollars

Number of pencil boxes = m

Price of a pencil box = 10 dollars

Hence, total price of m number of pencil boxes = 10m

Number of pen boxes = n

Price of a pen box = 12 dollars

Hence, total price of n number of pencil boxes = 12n

Therefore, the total price of pen and pencil boxes = (10m +12n) dollars
