If the new forecast is 24% more than the 5.6 billion estimated, we can calculate this as:
[tex]\begin{gathered} Y_{\text{new}}=Y_{\text{old}}+0.24\cdot Y_{\text{old}}=(1+0.24)Y_{\text{old}}=1.24\cdot Y_{\text{old}} \\ Y_{\text{new}}=1.24\cdot5.6=6.944\approx6.9 \end{gathered}[/tex]Answer: The total now is approximately 6.9 billion.
