title: Gurobi Function of Variables
body: <p>I have a function like this: <code>y = f(x) = a*(x/b) + c</code></p>
  
  <p>And I'd like to maximize <code>y</code> using Gurobi. Both <code>x</code> and <code>y</code> must be Gurobi Variables.</p>
  
  <p>How can I model this problem?</p>
  
  <p>P.S: <code>a</code>, <code>b</code> and <code>c</code> are numerical values.</p>
