Explanation / Answer

1) To convert the currency, 1800 pesos will be converted into dollars by using exchange rate of dollar-pesos. This implies dollar cost = 1800 pesos * $1/13 pesos

Hence option B is correct

2) As mentioned, the dollar cost of tyre is 1800/13 or $138. This is higher than the $129 per tyre. So he must buy the cheaper product from USA.

3) The demand curve for dollars exhibits the quantity of dollars demanded at various levels of exchange rate. So the correct option is C.
