Compare 17 and 12 plotted on the number line. What is the approximate difference in tenths between the two values?

It’s probably 50 but try writing a number line out and counting

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
