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
