while she was traveling in 2023, mai received 342.50 norwegian kroner in exchange for 50 australian dollars. determine the number of norwegian kroner mai would receive in exchange for 120 australian dollars

Answer

Explanation:

Step1: Find the exchange - rate

First, find out how many Norwegian kroner per Australian dollar. We know that for 50 Australian dollars, Mai received 342.50 Norwegian kroner. The exchange - rate $r$ is calculated by dividing the number of Norwegian kroner by the number of Australian dollars. So, $r=\frac{342.50}{50}=6.85$ kroner per Australian dollar.

Step2: Calculate for 120 Australian dollars

To find out how many Norwegian kroner for 120 Australian dollars, we multiply the number of Australian dollars by the exchange - rate. Let $x$ be the number of Norwegian kroner for 120 Australian dollars. Then $x = 120\times r$. Substituting $r = 6.85$ into the equation, we get $x=120\times6.85 = 822$ kroner.
