Step-by-step explanation:

Ken paid $12 for two magazines.the cost of each magazine was a multiple of $3.

The multiples of 3 less than 12 are 3,6 and 9.

Let the price of magazine 1 be 3 $

            Price of magazine 2 = 12 - 3 = 9$

Let the price of magazine 1 be 6 $

            Price of magazine 2 = 12 - 6 = 6$

Let the price of magazine 1 be 9 $

            Price of magazine 2 = 12 - 9 = 3$

So the magazine prices can be ( 3 $, 9 $ ) ,  ( 6 $, 6 $ ) and  ( 9 $, 3 $ )
