QuestionConvert 25,000 CAD to USD using the exchange rate of 1 USD = 1.329 CAD. Identify the two fractions for dimensional analysis.

Studdy Solution
Calculate the cost in USD.
$$Cost\, in\, USD =25,000\, CAD \\times \frac{1\, USD}{1.329\, CAD} = \$18,815.35$$The cost of the Toronto automobile in U.S. dollars is \$18,815.35.
The two fractions that are multiplied together to calculate the solution using dimensional analysis are1. The cost of the car in CAD, which can be written as a fraction with a denominator of1$$\frac{25,000\, CAD}{1}$$2. The conversion factor from CAD to USD$$\frac{1\, USD}{1.329\, CAD}$$These fractions cross-cancel the units of CAD, leaving the unit of USD, which is the desired unit for the answer.
