Answer:
104.76 yen per dollar
Step-by-step explanation:
the forward rate = spot rate x [(1 + foreign interest rate) / (1 + domestic interest rate)] = 100 yen x [(1 + 10%) / (1 + 5%)] = 100 yen x (1.1 / 1.05) = 104.76 yen per dollar
Since the interest rate in Japan is higher than the interest rate in the US, investors will start to purchase more yens in order to gain higher interest rates, which will eventually appreciate the yen against the dollar until both interest rates match.
