A grandfather distributes 4,500,000 among his three grandchildren, ages 8, 12 and 16; proportionally to his ages. How much corresponds to each one?

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
