a flow variable.
Profit and the balance on the balance of payments are flow variables. Therefore,
alternatives (3) and (4) are not correct alternatives.

Question text

Select one:
a.
the rand has depreciated
b.
American imports from South Africa will now cost less in terms of dollar.
c.
, the dollar has appreciated
d.
South African imports from America will now cost less in terms of rand.
Feedback
Your answer is incorrect.
South African imports from America will now cost less in terms of rand.
If the exchange rate changes from R15,55 = $1, to R14,90 = $1, it means that South
Africans will now pay less for one dollar. Therefore the rand has become stronger, we say
it has appreciated.
Americans will now receive less rand for every dollar; therefore, the dollar has
depreciated.
South Africans will now pay less for every dollar that they buy; therefore, American
products will now be relatively cheaper in South Africa than before the change in the
exchange rate.
However, Americans will now get less rand for every dollar; therefore, South African
products will now be relatively more expensive in America than before the change in the
exchange rate.
The correct answer is: South African imports from America will now cost less in terms of
rand.
