A car traveled 687.5 miles in 12.5 hours at a constant rate if distance is determined by the equation d=rt where r, is the constant rate in miles per hour how far will the car travel in 16 hours?

The first answer is correct

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
