I'm procrastinating please help hahaha

Hey dan. I'm Derek, me and my friend have a very important macro economics test tomorrow.!!! Can you be willing to answer me this little question? I'm in despair : " in the Mundell- Fleming context, as a consequence of an increase in the interest rate of the foreign economy: under a fix currency exchange, why does the central bank need to increase domestic interest by 4% to protect its coin.

Suppose you have i-i* +((Ee-E)/E))= -4 and perfect capital mobility.

Sorry for bad English I'm translating from Spanish
