Question

determina el descuento unico de 40%, 25% y 5%

Answer 1

Total = P -> 100%

descuento 40% queda 60%

descuento 25% queda 75%

descuento 5% queda 95%

(60/100)(75/100)(95/100)(P)

(6/10)(3/4)(95/100)(P)

(6/2)(3/4)(19/100)(P)

(3)(3/4)(19/100)(P)

(42,75/100)(P)

42,75%P

Du = 100%P - 42,75%P = 57,25%
