Can u tell me if my answers are correct here? a football star earns a $12 million annual salary in 2010. in 2015, he will earn $14,500,000. what is the rate of change of his salary per year? $500,000 per year $1,000,000 per year -$500,000 per year -$1,000,000 per year $1,000,000 per year is what i think, correct?

By the process of elimination, it is already not the last 2, so it is 50/50 chance to get it correct, but if you know how to add, you can figure out that 1 million per year in 5 years means that it is 12 million + 5 million, which is equal to 17 million and not 14,500,000. This brings it down only to 500,000$ salary increase per year

I’m not sure about that
