In 2022, XYZ Corp released the following sales figures:
12.33 million in revenue – 4.18 million in cost = 8.15 million in profit
In 2023, XYZ Corp’s costs tripled but their profit remained the same. How much was their revenue in 2023?
8.36 million
8.36 million

Read the explanation below on this concept or revist the lesson video.
Text Explanation:
Hence, the correct answer should be something close to 20 million. And that’s answer choice B.
And if you’re curious about the algebra, here it is:
2023’s revenue – 3 × 4.18 million = 8.15 million
2023’s revenue – 12.54 million = 8.15 million
2023’s revenue = 8.15 million + 12.54 million
2023’s revenue = 20.69 million
