To convert 80 US dollars (USD) to Australian dollars (AUD), you need to use the appropriate conversion rate. Given the conversion rate of 1 USD = 1.0343 AUD, the correct expression to use is:
[tex]\[ 80 \, \text{USD} \times \frac{1.0343 \, \text{AUD}}{1 \, \text{USD}} \][/tex]
Let's break down the process step-by-step:
1. Identify the conversion rate given: [tex]$1 \, \text{ USD} = 1.0343 \, \text{ AUD}$[/tex].
2. Multiply the amount in USD by the conversion rate to find the equivalent amount in AUD.
3. For 80 USD, this calculation becomes:
[tex]\[
80 \, \text{USD} \times 1.0343 = 82.744 \, \text{AUD}

Thus, the expression to convert 80 USD to AUD is:
[tex]\[ 80 \, \text{USD} \times \frac{1.0343 \, \text{AUD}}{1 \, \text{USD}} \][/tex]
And the equivalent amount in Australian dollars is 82.744 AUD.
