Review the table below. Note: the exchange rates are just examples for made up countries and are not intended to be accurate. You will use the information in the table and what you learned in the lesson to answer the questions that follow. Country and Currency Name
Today’s Currency Exchange Rate

Techtopia
(Techtopian dollar, or TPA)

1 USD = 1 TPA

Crosswater
(Crosswatering dollar, or CSW)

1 USD = 20 CSW

Nearland
(Nearlandian dollar, or NRD)

1 USD = 5 NRD

Remember how to calculate currency conversions:
To determine the currency conversion, multiply the amount of U. S. dollars by the currency exchange rate. For example, since the currency exchange rate for U. S. dollars to Nearlandian dollars is 1 USD = 5 NRD, then 20 U. S. dollars is equivalent to 100 Nearlandian dollars, because 20 x 5 = 100. If you have 50 Nearlandian dollars to convert back to U. S. dollars, you would divide by the exchange rate. Thus, 50 Nearlandian dollars is equivalent to 10 U. S. dollars, because 50 / 5 = 10.
1. 1. In at least two complete sentences, explain why a traveler will need to visit a currency exchange. Include how exchange rates are determined.

1. 2. You have $100 in the United States. Imagine you are visiting Crosswater to check out new products. How much would your $100 be in Crosswatering dollars? (Be sure to show your work.)

1. 3. You read about a new invention in Techtopia. You consider traveling there instead. How much would your $100 be in Techtopian dollars? (Be sure to show your work.)

1. 4. A computer part costs 200 TPA in Techtopia, and the same part costs 1,000 CSW in Crosswater. Figure out how much USD you need to buy the part from each country:
200 TPA = USD 1,000 CSW = USD
Now answer the question: Should you travel to Techtopia or to Crosswater to buy the part? Explain your answer and show your work.

1. 5. You buy certain supplies in Nearland. Last year, the currency exchange rate was 1 USD = 3 NRD. Are these supplies more or less expensive to buy now than last year? Explain your answer in complete sentences.
