As compared to its first year of operation, ABC Company grew 8% in the second year and an additional 2% per year for the next two years. If total growth for years 2-4 was $45,000 over the first year’s sales of $150,000, how much did ABC Company grow in year 2?

Answer 1

Discard the noise about years 3 and 4.
ABC grew 8% of 150,000 = 12000

As you can see, the numbers don't add up even close:

150000(1.08*1.02^2 - 1) = 18,544.80

Where did the 45,000 come from?
