Automobile repairs and maintenance cost Jana Padgett $900 last year. She drove 15,900
miles. To the nearest cent, what was her cost
per mile?

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
