172 boys in class
we have total number of students in class = 410
we assume that the number of boys in class = X
Number of girls in class is 66 more then boyes we assume total number of girls = X+66

Step-by-step explanation:
x - 2y = -4
x = 2y - 4
2y - 4 - 2y = -4
2y - 2y = 0
0 = 0
y = 0
x = 2 × 0 - 4
x = 0 - 4
x = -4
Company A: 23,000+(1,200x9)=33,800
Company B: 26,000+(800x9)=33,200
So, Company A pays $600 more than company B in year 10
The answer is 50.
