Sales tax is 5% what will be the sales tax on a purchase of $15.95

Get 40 cups.u would say since the bowl and cups must be equal it would be 40

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
