problem 5\nwhile she was traveling in 2023, mai received 342.50 norwegian kroner in exchange for 50 australian dollars.\nwrite an equation to represent the amount of norwegian kroner, n, received in exchange for a australian dollars.
Answer
Explanation:
Step1: Find the exchange - rate
The exchange - rate $r$ is calculated by dividing the amount of Norwegian kroner by the amount of Australian dollars. Given that 342.50 Norwegian kroner is received for 50 Australian dollars, so $r=\frac{342.50}{50}=6.85$.
Step2: Write the equation
The amount of Norwegian kroner $n$ received in exchange for $a$ Australian dollars is given by the equation $n = ra$. Substituting $r = 6.85$ into the equation, we get $n=6.85a$.
Answer:
$n = 6.85a$
