Given: The conversion rate below

[tex]1(rand)=0.08(dollars)[/tex]

To Deteremine: The worth of 168.18 rand in dollars

Solution

[tex]\begin{gathered} 1(rand)=0.08(dollars) \\ 168.18(rand)=x(dollars) \end{gathered}[/tex]

Let us cross multiply

[tex]\begin{gathered} x\times1=0.08\times168.18 \\ x=13.4544 \\ x\approx13.45(nearest-hundredth) \end{gathered}[/tex]

Hence, worth of 168.18 rand in dollars is approximately 13.45 U.S. dollars

(b) To Determine: How many rand was 59.09 dollars

[tex]\begin{gathered} Recollect \\ 1(rand)=0.08(dollars) \\ y(rand)=59.09(dollars) \end{gathered}[/tex]

Let us cross-multiply

[tex]\begin{gathered} 0.08\times y=1\times59.09 \\ 0.08y=59.09 \\ y=\frac{59.09}{0.08} \\ y=738.625 \\ y\approx738.63(rand) \end{gathered}[/tex]

Hence, 59.09 dollars is worth approximately 738.63 rands
