Question 250291: Sara earns 6 dollars an hour more than her assistant. During an 8 hour day they earn 240 dollars. How much does each earn per hour Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! let s= sara per hour
a=assistant per hour
s=6+a
8*s+8*a=240
substitute 6+a for s in second equation
8*(6+a)+8*a=240
after finding a, substitute that value in this equation to find s
s=6+a
