Answer 1

Answer:

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

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.
