Important examples of billion in TOEIC

Vocabulary examples from the TOEIC test

In TOEIC vocabulary questions, billion often refers to a large number in business contexts.

▪The project costs one billion dollars.
▪The project costs a large amount of money.

Example of a confusing word: million (a smaller numerical value)

▪The project costs one million dollars.
▪The project costs a smaller amount of money.
"Billion" refers to a numerical value of 1,000,000,000, which is significantly larger than "million," which is 1,000,000. In business contexts, using "billion" indicates a much larger scale of financial transactions or quantities. The sentence "The project costs one billion dollars" is grammatically correct and accurately reflects a large expenditure. In contrast, "million" represents a smaller amount, and using it would change the scale of the project cost significantly. Therefore, "billion" is the correct choice for expressing a very large sum.
