Question

In 2020, a company’s revenue was $105,000,000, while in 2021 its revenue reached $135,000,000. How much higher was the company’s revenue in 2021 than in 2020? Write the answer in scientific notation

Answer 1

To find the difference in revenue between 2021 and 2020, we subtract the revenue in 2020 from the revenue in 2021: $135,000,000 - $105,000,000 = $30,000,000.

The answer in scientific notation would be $3.0 × 10^7.
