Two friends sold many pieces of furniture and made $950 during their garage sale. They had thirteen more $10 bills. They had 5 more than three times as many as many &20 bills as $50 bills. How many of each denomination do they have?

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
