Respuesta :

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.
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
