+576 When you say "solve" I assume you're looking for a value of x that makes the two equations equal so my response will be regarding that goal.
First set the two equations equal to one another
R(x)=C(x)
60x-.4x^2=3x+13
Let's move all of our terms to the right side so our quadratic term is positive
0=.4x^2 -57x+13
From here you will want to use the quadratic formula to find your answer(s).
