Answer:
La base salarial de cada trabajador es de $ 425
Step-by-step explanation:
Aquí queremos calcular la base salarial de cada trabajador
Antes del incremento, sea la base salarial $ x
Entonces, sin el incremento, lo que ganarán los 3 es x + x + x = 3x
Con el incremento, cada uno ganará 3 (x + 50)
Esto es lo que es igual a 1425 Así; 3 (x + 50) = 1425
x + 50 = 1425/3
x + 50 = 475
x = 475 - 50
x = 425
