Question
45,000= 150r + 250s

Answer
First of all, never, never use a comma in an equation.  What do you want to do with that?   You can divide by 50 to get 900 = 3r+5s.  You can't solve for r or s independently with only one equation. That's an equation of a straight line and you can plot r vs. s.
