    The cost of 9 pens would be $3.60.

    to get that answer first you see how much 1 pen is, so you divide $2.40 by 6 gives you. 40 cents. So you multiply. 40 by 9 and you get = $3.60

    9 pens would cost you $3.6 because if you divide $2.40 by 6 you get 0.4.

    0.4 is the cost per pen.

    Multiply 9 by 0.4 and you get $3.6.
