Instead of adding large numbers together, we can find the residue for each person for easier computation. We convert the amount they earned to cents and find the modulo $ 100 $ for each. \begin{align*} 2747 &\equiv 47 \pmod{100},\\ 3523 &\equiv 23 \pmod{100},\\ 3737 &\equiv 37 \pmod{100},\\ 2652 &\equiv 52 \pmod{100} \end{align*}We want to find the modulo $ 100 $ of the total number of cents. We can add the separate residues to get $$47+23+37+52 \equiv 159 \equiv 59 \pmod{100}$$Therefore, they have $ \boxed{59} $ cents left after converting as much of the money into bills as possible.
