At the end of Daniela’s holiday she has 370 Argentinean peso (ARS). She converts this back to USD at a bank that charges a 4% commission on the exchange. The exchange rate is 1 USD = 9.60 ARS.
Calculate the amount of PEN she receives.

\((85 - 5) \times 3.25\) (M1)(M1)
Note: Award (M1) for subtracting 5 from 85, (M1) for multiplying by 3.25.
Award (M1) for \(85 \times 3.25\), (M1) for subtracting \(5 \times 3.25\).
\( = 260{\text{ (PEN)}}\) (A1) (C3)
[3 marks]
\(\frac{{(370 \times 0.96)}}{{9.6}}\) (M1)(M1)
