Mr. Smith's salary has increased by 350% over the past 20 years. If his original salary was $22,000 per year, what is his current salary?

First change 350% to a decimal: 350% = 3.5

Next, multiply the original salary by the decimal number: (22000) x (3.5) = 77000

After 20 years Mr. Smith's salary has increased from $22,000 to $77,000 per year.

Didn't his salary increase by $77,000, from $22,000 to $99,000?

To simplify it, if his salary had increased by 100% would that mean he was now making $22,000 (their logic) or $44,000 (my logic)?
