According to the World Alamanac of 2005, Muhammed emerged as a prophet in 610 A. D. Which is a close estimate to about how many years have elapsed since then? Pls i need help

The answer should be 5.

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
