Write a word phrase to represent the algebraic expressions 2x + 4

When i babysit, i get 4 dollars for showing up, and them 2 dollars for every hour that im there. X=hours

If the answer isn't: two times x plus four, then im guessing it's something like:
i eat 2 doughnuts per day for x days plus 4 doughnuts when i first bought the box.  sorry if i misinterpret the question.

Something that is true about that is that it has numbers
