Question

Say you are going on a trip for a manufacturing company to Italy and need to find out the currency conversion. You are going to take 1500 US dollars. After checking the internet you find the exchange rate is ONE US dollar to every 0.74 euros. Task:First, write an equation to convert US dollars into Euros.Secondly, explain how many Euros you will have if you converted all 1500 US dollars.Thirdly, if on your return trip you need to calculate how many US dollars you have left you will need to inverse the original equation. What is this inverse equation?Lastly, if after a trip you have 75 euros left how much US dollars is that?

Answer 1

To convert US dollars into Euros, use the equation: Euros = US dollars * Exchange rate. If you converted all 1500 US dollars at an exchange rate of 0.74 euros per dollar, you will have 1110 euros. The inverse equation is US dollars = Euros * (1/Exchange rate). If you have 75 euros, that is approximately 101.35 US dollars.

Step-by-step explanation:

To convert US dollars into Euros, you can use the equation:

Euros = US dollars * Exchange rate

Using the exchange rate of ONE US dollar to every 0.74 euros, we can substitute the values into the equation:

Euros = 1500 US dollars * 0.74

Calculating, you will have 1110 euros if you converted all 1500 US dollars.

To find the inverse equation, you simply swap the positions of US dollars and euros:

US dollars = Euros * (1/Exchange rate)

Using the original exchange rate of ONE US dollar to every 0.74 euros, the inverse equation would be:

US dollars = Euros * (1/0.74)

If you have 75 euros left and want to find out how much US dollars that is, you can use the inverse equation:

US dollars = 75 euros * (1/0.74)

Calculating, you will have approximately 101.35 US dollars.
