44. travel roscoe is exchanging $121 for euros for his upcoming trip to germany. if $2 can be exchanged for 1.78 euros, how many euros will roscoe have?
Answer
Explanation:
Step1: Set up the proportion
Let $x$ be the number of Euros. The proportion is $\frac{1.78}{2}=\frac{x}{121}$.
Step2: Cross - multiply
$2x = 1.78\times121$.
Step3: Calculate the right - hand side
$1.78\times121=215.38$, so $2x = 215.38$.
Step4: Solve for $x$
$x=\frac{215.38}{2}=107.69$.
Answer:
107.69
