Let A=adults; B=students 
A+B=250 (total number of people) 
$4(A)+$1(B)=$427 (total earned) or 4A+B=427 

A+B=250 
B=250-A 

4A+B=427 
substitute B with (250-A) 
4A+250-A=427 
4A-A+250=427 
3A+250=427 
3A=427-250 
3A=177 
A=177 / 3 
A=59 adults 

A+B=250 
B=250-A 
B=250-59 
B=191 students 

the answer is A) 191
