Answer:
The amount of rand he will collect when $19.50 was exchanged to rand is;
[tex]27.75\text{ rands}[/tex]Explanation:
Given that the exchange rate is $5.20= 7.4 rand;
[tex]\begin{gathered} \text{ \$5.20 }\rightarrow\text{ 7.4 rands} \\ \text{ \$1 }\rightarrow\frac{7.4}{5.2}\text{ rands} \end{gathered}[/tex]So, for $19.50, we have;
[tex]\begin{gathered} \text{ \$19.50 }\rightarrow\frac{7.4}{5.2}\times19.50\text{ rands} \\ \text{ \$19.50 }\rightarrow27.75\text{ rands} \end{gathered}[/tex]Therefore, the amount of rand he will collect when $19.50 was exchanged to rand is;
[tex]27.75\text{ rands}[/tex]
