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
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.
