Una clase de 32 se dividen para ir al cine y el otro grupo a la piscina. Si la entrada de la piscina cuesta 2,5 euros y la del cine 3,5 euros y se han gastado un total de 94 euros, ¿cuantos niños componían cada grupo?.

14 children went to the movies and 18 went to the pool.

14 niños en el grupo del cine y 18 en el grupo de la piscina.

Step-by-step explanation:

We can solve this question using a system of equations.

I am going to say that:

x is the number of children that went to the movies.

y is the number of children that went to the pool.

Class of 32:

This means that

To go to the pool, it costs 2.5 euros. To go the movies, it costs 3.5 euros. 94 euros were spent.

This means that

From the first equation:

Replacing in the second

14 children went to the movies and 18 went to the pool.

14 niños en el grupo del cine y 18 en el grupo de la piscina.

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
