1.a) 120000 - 2/3*px + (120000 – 2/3 – 1000) *px/2 = 1492500

80000 px + 19500 px = 1492500

99500 px =1492500

px = 1492500 / 99500

px = 15

RTA 1: El precio original es de $15

b) (120000-2/3) * 15 + (120000-2/3-1000) *15/2 - (120000-10) = X80000 * 15 + 39000 * 15/2 - (1200000) = X

1200000 + 292500 - 120000 = X

292500 = X

RTA 2: El resultado de la campaña esde 292500.

2.a) Ecuación general de una recta Y = mx + b (m = pendiente y b = ordenada al origen).
