Suppose that on November 26, 2019, an ornamental bookcase handmade in Germany is priced at EUR 830. The approximate U.S. dollar
Klio2033 [76]

The <em>approximate</em> price for an ornamental bookcase from Germany and with a cost of EUR 830 on November 26, 2019 is equal to 753.64 USD.

<h3>How to determine the price of a good in terms of a foreign currency</h3>

Herein we have an application of <em>direct proportionality</em> model, now described:

y = k · x     (1)

Where:

  • x - Cost of the bookcase in Germany, in euros.
  • k - Currency exchange rate, in US dollars per euros.
  • y - Cost of the bookcase in the United States, in US dollars.

If we know that x = 830 EUR and k = 0.908 USD/EUR, then the cost of the bookcase in the United States is:

y = (830 EUR) · (0.908 USD/EUR)

y = 753.64 USD

The <em>approximate</em> price for an ornamental bookcase from Germany and with a cost of EUR 830 on November 26, 2019 is equal to 753.64 USD.
