How to draw this in latex - Diagrams and graph of functions

Question

I would like to draw this in TikZ. Here is what I have tried.
begin{tikzpicture}[->,scale=1.5]
   node (i) at (120:1cm)  {Money invested};
   node (j) at (-125:.7cm) {Interest rate};

draw (67:1cm)  arc (50:-50:1cm);
   draw (-160:1cm) arc (-150:-180:1cm);
end{tikzpicture}

Here is a start:
documentclass[tikz]{standalone}

begin{document}
 begin{tikzpicture}[->,scale=1.5]

path (120:1cm) node (i) {Money invested}
   +(0,-1cm) node (j){Interest rate}
   +(0,-.5cm)node(R){R};

begin{scope}[bend left=90,looseness=2,pos=0.95,below,node font=tiny]
        draw (i)to []node[]{+}(j);
        draw (j)to[] node[]{+}(i);
        draw (R.45)arc[radius=0.25,start angle=45,delta angle=-180];
   end{scope}

end{tikzpicture}
end{document}
