To solve this, we just have to subtract the numbers.


That's our solution set.
Have a nice day! :)
Answer:
El Ministerio de Educación recibió el 5.99% del presupuesto nacional.
Step-by-step explanation:
Dado que en El Salvador el presupuesto de gastos para el año 2020 fue de 500 millones dos cientos cincuenta mil dólares, de los que le correspondieron $30,000,000 al Ministerio de Educación, para determinar qué tanto por ciento le fue asignado se debe realizar el siguiente calculo:
500.250.000 = 100
30.000.000 = X
30.000.000 x 100 / 500.250.000 = X
3.000.000.000 / 500.250.000 = X
5.99 = X
Por lo tanto, el Ministerio de Educación recibió el 5.99% del presupuesto nacional.
The first thing we must do for this case is to define a variable.
We have then:
x: number of phones that were sold at the wrong price.
y: number of phones that were sold with the correct price.
We now write the system of equations that represents the problem.
We have then:

Resolving the system graphically we have:

Note: see attached image for the graphic solution.
Answer:
234 phones were sold at the wrong price
First find all of the factors of 7 and 4:
7: 1, 7
4: 1, 2, 4
They don't have any other factors except for 1.
So the greatest common factor of 7 and 4 is 1.
Hope this helps :)
