Answer:
... the dollar is said to have depreciated (in relation to the yen) and the yen has appreciated (in relation to the dollar)
Step-by-step explanation:
Appreciation means a rise in value. Depreciation means a fall in value.
From $1 = 100 yen to $1.50 = 100 yen:
- 100 yen can be exchanged for more dollars (1 instead of 1.5) => the yen has appreciated
- it takes more dollars (1.5 instead of 1) to exchange for 100 yean => the dollar has depreciated
