The function we have to use in this case is

m(t)=m_o\cdot(1+\frac{0.03}{4})^{4t}

where mo is the initial amount of money. After 2 teats we get that

\begin{gathered} m_0\cdot(1+\frac{0.03}{4})^8=800 \\ m_0\cdot1.06=800 \\ m_0=\frac{800}{1.06}\approx754.71 \end{gathered}

SO he earned 755 approximately
