Find the number of statues that are non-defective.

The manufacturer sells each non-defective statue for \(5.25\) British pounds (GBP) to an American company. The exchange rate from GBP to US dollars (USD) is \(1{\text{ GBP}} = 1.6407{\text{ USD}}\).

Calculate the amount in USD paid by the American company for all the non-defective statues. Give your answer correct to two decimal places.

The American company sells one of the statues to an Australian customer for \(12{\text{ USD}}\). The exchange rate from Australian dollars (AUD) to USD is \(1{\text{ AUD}} = 0.8739{\text{ USD}}\) .

Calculate the amount that the Australian customer pays, in AUD, for this statue. Give your answer correct to two decimal places.

\(0.88 \times 16000\)     OR     \(16000 - 0.12 \times 16000\)     (M1)

\(14080\)     (A1)     (C2)

[2 marks]

\(1.6407 \times 5.25 \times 14080\)     (M1)

\(121 280.54{\text{ USD}}\)     (A1)(ft)     (C2)

Note: Follow through from their answer to part (a).

[2 marks]

\(12 \times \frac{1}{{0.8739}}\)     (M1)

\(13.73{\text{ AUD}}\)     (A1)     (C2)

Note: If division used in part (b) and multiplication used in part (c), award (M0)(A0) for part (b) and (M1)(A1)(ft) for part (c).

This question was generally well answered with much correct working seen in parts (a) and (b). The most popular incorrect answer in part (a) was \(1920\) – candidates simply stating the number of defective items rather than the number of non-defective items. Unfortunately in part (c) many candidates multiplied by \(0.8739\) rather than divided and \(10.49\) proved a popular, but erroneous, answer.
