Además, $40$ estudiantes eran de Jones Middle School y $60$ eran de Clay Middle School. Veinte de las niñas eran de Jones Middle School. ¿Cuántos de los niños eran de Clay Middle School?

Last summer $100$ students attended basketball camp. Of those attending, $52$ were boys and $48$ were girls. Also, $40$ students were from Jones Middle School and $60$ were from Clay Middle School. Twenty of the girls were from Jones Middle School. How many of the boys were from Clay Middle School?

$20$

$32$

$40$

$48$

$52$

Solución:

Como asistieron $48$ niñas y $20$ eran de Jones, $48 - 20 = 28$ niñas eran de Clay.

Clay tenía $60$ estudiantes en total, así que el número de niños de Clay es $60 - 28 = 32.$

Por lo tanto, la respuesta correcta es B.

Since $48$ girls attended and $20$ were from Jones, $48 - 20 = 28$ girls were from Clay.

Clay had $60$ students total, so the number of Clay boys is $60 - 28 = 32.$

Thus, the correct answer is B .
