Just drop the last two zeros and you have the number of dollars, $9,000,000.
900000000
It's likely that C was going to be the answer since A and B were incorrect. We don't know if there was going to be a D. Here's the correct answer: 5000000000 + 900000000 + 80000000 + 2000000 + 700000 + 50000 + 7
Oh, isn't that a lovely number? Let's paint a picture with words for it. 900,000,000 in words is "nine hundred million." Just imagine all the happy little zeros dancing together in harmony, creating such a peaceful and vast number.
Nine hundred million.
900000000-100000000 = 800000000
