Question

En un partido de fútbol las entradas valen s/80 y s/40. Si se vendieron en total 10000 entradas y se recaudo 480000 soles¿Cuantas entradas de 40 se vendieron? (S/ =Soles)

Answer 1

80x+40(10,000-x)=480,000
80x+400,000-40x=480,000
400,000-40x+80x=480,000
400,000+40x=480,000
40x=480,000-400,000
40x=80,000
X=80,000/40
X=2000

2000+y=10,000
Y=10,000-2,000
Y=8,000

X=2,000 (s/80)= 160,000
Y=8,000 (s/40)= 320,000

X+ Y= 480,000
