  $22.20

Step-by-step explanation:

It can work well to translate the problem statement directly to a math statement, then solve.

  English: 13.32 is 3/5 of the cost

  Math: 13.32 = 3/5 · (the cost)

Now you can see that solving this equation for (the cost) means you divide by 3/5, or, equivalently, multiply by 5/3.

  (5/3)·13.32 = (5/3)·(3/5)·(the cost)

  22.20 = the cost

The present cost $22.20. . . . . . . It's a good idea to write the answer as a clear, complete sentence in response to the question that is asked, preferably using the same terminology.
