En una secundaria, la maestra de historia organizó una visita al Museo de Arte. Asistieron 75 alumnos de primero y 69 de
segundo grado. Para cubrir los gastos cada alumno aportó
$75.00, excepto 24 que solo aportaron $50.00. Los boletos
de entrada al Museo costaron $17.25 cada uno, pero por
tratarse de un grupo regalaron 1 boleto por cada 9 que
compraron.
¿Cuánto dinero se reunió en total para la visita al Museo?
A) $7,800
B) $10,200
C) $9,800
D) $10,800

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
