The company, hewerrtt, would like to make letter codes using all of the letters in the word hewerrtt. how many codes can be made from all the letters in this word?

If the company, hewerrtt, would like to make letter codes using all of the letters in the word hewerrtt, they would be able to make five codes. Altogether, there are eight letters in the word, but there are duplicates of the letter e, the letter r, and the letter t, so that takes out three possibilities. Three subtracted from eight is equal to five, therefore the company can make five codes using the company name.

You just did...
