# School year

At the end of the school year has awarded 20% of the 250 children who attend school. Awat got 18% boys and 23% of girls. Determine how many boys and how many girls attend school.

Result

x =  150
y =  100

#### Solution:

x+y = 250
0.18x+0.23y = 0.2*250

x+y = 250
0.18x+0.23y = 50

x = 150
y = 100
