The answer to this question would be 29,032,000,000
In this question, you are given number in written form and asked to convert it into standard form. To answer this question, it will be easier to split the sentences into multiple parts like this:
1. "twenty-nine billion" mean 29 * 1,000,000,000 =29,000,000,000
2. "thirty-two million" mean 32* 1,000,000= 32,000,000
Then, if you add them up it will be: 29,000,000,000 + 32,000,000= 29,032,000,000
