Answer:14%
Step-by-step explanation:
final grade score=a
20% of a=15
20/100 x a=15
20a/100=15
Cross multiply
20a=15 x 100
20a=1500
Divide both sides by 20
20a/20=1500/20
a=75
B% of 75=10.5
B/100 x 75=10.5
75B/100=10.5
Cross multiply
75B=10.5 x 100
75B=1050
Divide both sides by 75
75B/75=1050/75
B=14

I have to assume that you want the answer in Spanish *but without using accents).
Usa las siguientes variables:
d = numero de habitaciones dobles
i = numero de habitaciones individuales
Por la primera premisa:
d + i = 180
Por la segunda premisa, los costos son tales que:
78d + 72i = 7839
Para resolver ese sistema podemos despejar una de las variables de la primera ecucacion y sustituir en la segunda:
i = 180 - d
78d + 72 (180 - d) = 7839
78d + 12960 - 72d = 7839
De aqui ya veo que va a dar un numero negativo para el numero de habitaciones dobles, asi que supongo que algun dato en el enunciado esta equivocado.
6d = 7839 - 12960 = -5121
=> d = -5121 / 6 = - 853.5
Al corregir los datos podras seguir el procedimiento que te he explicado para encontrar la solucion.
