Lo que tenia Mayra = 95 soles
Lo que gasto = x
Lo que no gasto = 95 - x
x = 1/2 de 1/4 de los 4/9 de (95 - x)
x = 1/2 * 1/4 * 4/9 (95 - x)
x = (1 * 1 * 4)(95 - x)/9
x = 4(95 - x)/(2 * 4 * 9)
x = (380 - 4x)/72
72x = 380 - 4x
72x + 4x = 380
76x = 380
x = 380/76
x = 5
Respuesta.
Mayra ha gastado 5 soles
Total = 95 soles
Gastó = s
s = 1/2 de 1/4 de los 4/9 de (95 - s)
s = (1/2) (1/4) (4/9) (95 - s)
s = (4 (- s + 95) / (2 * 4 * 9)
s = (- s + 95) / (2 * 9)
19s = 95
s = 95/19
s = 5
Respuesta final.
Gastó solamente 5 soles
