Answer:
B. 25%
Step-by-step explanation:
25 percent of 60 would be 15, then if you subtract 15 from 60, you end up with 45, meaning that 25 percent was subtracted.
If you ask 100 people and 60 say they are students, then you would assume that 60/100 people in town as a whole are students. To estimate the non-student population, you would infer that the other 40 are not students, thus making the non-student to student ratio 40:60 or 2:3 when simplified. This means that for every 2 non-students, there are 3 students. If we multiply 2000 by this 2:3 ratio, we would see that 2/3*2000 = the non-student population.The non-student population is estimated at 1,333.
Answer:
72, 216 , 252
Step-by-step explanation:
Deje que lo que ella leyó inicialmente sea x páginas.
La segunda semana leyó 3 veces esto = 3 * x = 3x.
La tercera semana leyó 5 veces la primera semana menos 108 = 5x-108.
Así que agreguemos todos juntos para obtener x. 3x + x + 5x-108 = 540.
9x = 540 + 108 9x = 648 x = 648/9 = 72 páginas.
Leyó 72 páginas la primera semana.
Ella leyó 3 * 72 en la segunda semana = 216 páginas En la tercera semana leyó 5 (72) -108 = 360-108 = 252 páginas
