ira [324]

Answer:

Juan imprimió 7 páginas a color.

Step-by-step explanation:

Llamemos "b" a las copias en blanco y negro y "c" a las copias en color.

Juan imprimió 75 páginas. En forma simbólica es:

b + c = 75

b = 75 - c [1]

El costo de impresión de cada página en una biblioteca es de 5 centavos si es en blanco y negro o 50 centavos si es a color. En total pago $6.90. En forma simbólica es:

0.05b + 0.5c = 6.90 [2]

Si reemplazamos [1] en [2],

0.05(75-c) + 0.5c = 6.90

3.75 - 0.05c + 0.5c = 6.90

0.45c = 3.15

c = 7
