A piece of land with an area of .5 square kilometers is priced at $5700 Canadian. If there are 1.269 Canadian dollars per (US) dollar, then what is the price in dollars per square mile?

x US/5700 CND = 1/1.269

x = 5700/1.269 = 4491.73

better update your textbook, the two currencies since the Bush era have been roughly at par
(today $1.00 US = 1.03 CND)

To calculate the price in dollars per square mile, we need to convert the area from square kilometers to square miles and then determine the price per square mile.

1. Convert the area from square kilometers to square miles:
- Since 1 kilometer is approximately equal to 0.621371 miles, we can multiply the area in square kilometers by this conversion factor.
- So, area in square miles = 0.5 square kilometers * 0.621371 square miles per kilometer ≈ 0.3107 square miles.

2. Determine the price per square mile:
- To find the price per square mile, we divide the total price in Canadian dollars by the area in square miles.
- According to the given information, the land is priced at $5700 Canadian.
- Therefore, price per square mile = $5700 Canadian / 0.3107 square miles ≈ $18348.96 Canadian dollars per square mile.

Now, since there are 1.269 Canadian dollars per US dollar, we can convert the price from Canadian dollars to US dollars.

3. Convert the price from Canadian dollars to US dollars:
- We multiply the price per square mile in Canadian dollars by the exchange rate.
- So, price per square mile in US dollars = $18348.96 Canadian dollars per square mile * 1.269 US dollars per Canadian dollar ≈ $23279.59 US dollars per square mile.

Therefore, the price of the land in dollars per square mile is approximately $23279.59.
