Given the function
question in attachment

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

It would be b because if you look to the diagram there says 92 and then x and then go trough 115
