Answer:
B, 110
Step-by-step explanation:
Work Backwards! 
1.- 260 - 110 = 150 children
2.- 150 X $2.50 (rate of children) = $375
3.- $815 - $375 = $440 
4.- $440/$4 (rate of adults) = 110 Adults
 
        
             
        
        
        
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = -  x + 4 ← is i slope- intercept form
 x + 4 ← is i slope- intercept form
with slope m = - 
Parallel lines have equal slopes, thus
y = -  x + c ← is the partial equation
 x + c ← is the partial equation
To find c substitute (6, 5) into the partial equation
5 = - 2 + c ⇒ c = 5 + 2 = 7
y = -  x + 7 ← equation of parallel line
 x + 7 ← equation of parallel line
