A recipe says to use 4 cups of flour to make 60 cookies. What is the constant of proportionality that relates the number of cookies made, y , to the number of cups of flour used, x ?

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
