Question

Scott found a rare comic book on an online auction site priced at 35 Australian dollars. If the exchange rate is $1 U.S=$1.09 Australian, find the cost of the comic book in United States dollars. Round to the nearest cent

Answer 1

1 US = 1.09 Australian

divide by 1.09 on both sides to find how much a 1 Australian dollar is worth.

1/1.09 = 1 Australian dollar
1 Australian dollar = 0.92 US dollar

mulitply 35 on both sides of the equation

35 Australian = 35 (0.92) = 32.2 US dollars
