Final answer:
To determine the price of Minnesota ore in C$ per metric tonne, we need to convert the given price in US$ per short ton to C$ per metric tonne.
Step-by-step explanation:
To determine which source is more expensive, we need to convert the price of the Minnesota ore to C$ per metric tonne. Starting with the price given in US$ per short ton, we can convert it to US$ per metric tonne by multiplying by 0.9072 (since 1 short ton is equal to 0.9072 metric tonnes). Next, we can convert US$ to C$ by dividing by the exchange rate of C$1.1400 = US$1.00. Finally, we can round the result to the nearest cent.
Let's perform the calculations:
Price of Minnesota ore in US$ per metric tonne = US$110 / 0.9072 = US$121.0804
Price of Minnesota ore in C$ per metric tonne = US$121.0804 / C$1.1400 = C$106.2709
Therefore, the price of Minnesota ore in C$ per metric tonne is C$106.2709.
