Sum the expenses in US dollars

Using the Table Reading knowledge point
\[
\text{USD Subtotal} = 71.75 + 138.10 = 209.85
\]

Sum the expenses in South African rands

Using the Table Reading knowledge point
\[
\text{ZAR Subtotal} = 216.41 + 702.33 + 996.78 + 3,741.85 = 5,657.37
\]

Convert South African rands to US dollars

Using the Currency Conversion knowledge point
\[
\text{ZAR in USD} = \frac{5,657.37}{7.4094} \approx 763.5395
\]
Rounding to two decimal places:
\[
\text{ZAR in USD} \approx 763.54
\]

Calculate the total budget in US dollars

Using the Budget Calculation knowledge point
\[
\text{Total Budget} = 209.85 + 763.54 = 973.39
\]
