djyliett [7]

Answer:x=20

Step-by-step explanation:

Given

selling Price of Toy is x dollars

he can sell 40-x toys each week

Thus Revenue Generated from selling 40-x toys at x dollar can be given by

$R=-x^2+40x$

To get maximum Revenue differentiate R with respect to x and equate it to 0

therefore $\frac{\mathrm{d} R}{\mathrm{d} x}=-2x+40$

$-2x+40=0$

$x=20$

thus for maximum Revenue owner sells 20 toys each week

Max Revenue $R=-(20)^2+40\times 20=-400+800=$ 400$
