De la pregunta, podemos suponer que:
El costo del vestido = D
El costo de la bolsa = B
El costo de los zapatos = S
Entonces, será:
D = B + 35 --> B = D - 35
S = 3D
Y:
B + D + S = 380
(D - 35) + D + 3D = 380
D - 35 + D + 3D = 380
5D = 380 + 35
5D = 415
D = 83
Entonces,
B = D - 35 = 83 - 35 = 38
S = 3D = 3 x 83 = 249
Respuesta:
Bolsa = 48
Vestido = 83
Zapatos = 249
