Question

Between April 12, 2008, and April 12, 2013, the price of a U.S. postage stamp increased from $0.41 to $0.46. The price of a U.S. postage stamp has increased approximately ____________ in terms of Japanese yen and _____________ in terms of British pounds

Answer 1

Without the specific exchange rates for April 12 in 2008 and 2013, we cannot calculate the exact changes in terms of Japanese yen and British pounds for the U.S. postage stamp price increase from $0.41 to $0.46. However, general trends in exchange rates during that period include a depreciation of the yen around 2013 and an appreciation of the dollar relative to the pound from 2008 to 2017.

Step-by-step explanation:

The student's question pertains to the change in the price of a U.S. postage stamp from $0.41 to $0.46 between April 12, 2008, and April 12, 2013, and requires an analysis of how this price increase translates into Japanese yen and British pounds, considering the fluctuating exchange rates over time. To calculate the increase in terms of yen, we would need the exchange rates of the U.S. dollar to yen for the relevant years. Similarly, to determine the change in terms of pounds, we would need the pound to dollar exchange rate for those years. However, given the data and exchange rates provided, along with the time frame, we cannot precisely answer the question without the specific exchange rates for the exact dates in question, April 12 in 2008 and 2013. We need to take note of the exchange rate trends observed: the yen showed significant volatility with a depreciation around 2013 and a subsequent appreciation, while the British pound was weaker in 2017 compared to 2008, indicating that the dollar appreciated versus the pound during this period.

Answer 2

The price of a U.S. postage stamp has increased 10% in terms of Japanese yen and 44% in terms of British pounds.

Step-by-step explanation:

The exact question is as follows :

To find - Between April 12, 2008, and April 12, 2013, the price of a U.S. postage stamp increased from $0.41 to $0.46. The price of a U.S. postage stamp has increased approximately ____________ in terms of Japanese yen and _____________ in terms of British pounds.

Solution -

Given that,

postage stamp increased from $0.41 to $0.46

Now,

From the table, we can find that,

For, April 12, 2008

1$ = 0.5069 £

1$ = 101.54 ¥

And

For April 12, 2013

1$ = 0.6510 £

1$ = 99.62 ¥

Now,

We have -

1$ = 0.5069 £

⇒$0.41 = 0.207829 £

and

1$ = 0.6510 £

⇒$0.46 = 0.29946 £

So,

Change = (0.29946 - 0.207829)/ (0.207829) × 100 %

= 44%

∴ we get

The price of a U.S. postage stamp has increased 44% in terms of British pounds.

Now,

Similarly, we do for Japanese Yen

We have -

1$ = 101.54 ¥

⇒0.41$ = 41.6314 ¥

And

1$ = 99.62 ¥

⇒0.46$ = 45.8252 ¥

So,

Change = (45.8252 - 41.6314)/ 45.8252 × 100 %

= 10%

∴ we get

The price of a U.S. postage stamp has increased 10% in terms of Japanese yen.
