Understand exchange rate: Understand the exchange rate and what is being asked. $\newline$ Lilia wants to exchange US dollars for Euros. The exchange rate is $1$ US dollar to $0.84$ Euros. She wants to receive $350$ Euros. We need to calculate how many US dollars she needs to exchange to get $350$ Euros.
Set up equation: Set up the equation to find out how many US dollars Lilia needs. $\newline$ If $1$ US dollar equals $0.84$ Euros, then we can set up the equation as follows: $\newline$ $\frac{1 \text{ US dollar}}{0.84 \text{ Euros}} = \frac{X \text{ US dollars}}{350 \text{ Euros}}$ $\newline$ We need to solve for $X$ , which represents the amount in US dollars that Lilia needs to exchange.
Solve for X: Solve for X by cross-multiplying to find the number of US dollars. $\newline$ $X$ US dollars $*$ $0.84$ Euros = $1$ US dollar $*$ $350$ Euros $\newline$ X = (\(1 $*$ $350$ ) / $0$ . $84$ \) $\newline$ $X = 350 / 0.84$
Calculate value of X: Calculate the value of $X$ . $X = \frac{350}{0.84}$ $X \approx 416.6667$
Round to nearest whole number: Round the number to the nearest whole number since we are dealing with currency and cannot have a fraction of a dollar. $X \approx 417$
