Love playing but 25 bucks to expand, too much

I love cooking the different recipes. Im on level 10 and the task says to expand. I look to see what I need to expand and am shocked that it takes 25 bucks. I have earned about 5 bucks in the 3 days Ive been playing. At this rate, I wont be able to earn enough to upgrade until next week! Gone are the days where you bought the game outright and played until you were done. Other than this problem, I enjoy the game very much.
