Kim bought a poster that cost $8.94 and some colored pencils. the total price was $21.35 how much did the color pencil cost?

To solve you need to subtract 8.94 from 21.35 giving you 12.41 the coast of the pencils. 

21.35 - 8.94=12.41
colored pencils price: $12.41

you can check your answer by adding 12.41 to 8.94 to see if it adds up to the original total. It does so we know our answer is correct.

8.94+12.41=21.35

Hope this was helpful :)
