Answer:
Cantidad de aprobados= 25
Step-by-step explanation:
Dada la siguiente información:
Reproado= 45%
Aprobado= 55%
Cantidad de alumnos= 45 alumnos
<u>Para calcular la cantidad de aprobados, debemos utiliar la siguiente formula:</u>
<u />
Cantidad de aprobados= cantidad de alumnos*porcentaje aprobados
Cantidad de aprobados= 45*0.55
Cantidad de aprobados= 25
Create equations:
10X+15y=2575.
X+Y=210.
Solve for X: X=210-Y, and sub it into the other equation: 10(210-Y)+15Y=2575. Solve for Y: 2,100-10y+15y=2575, 5y=475, y=95.
Sub Y into the original problem: X+95=210. Solve: X=115.
The first mechanic charges $115 per hour and the second charges $95 :)
