Chris needs to buy a new stove in 5 years. He starts to deposit money quarterly, with the first saving in 3 month. If his investment earns 5% APR compounded semi-annually, how much he should invest every three month to buy a $2000 stove in 5 years? (Round your answer to two decimals.)

How much wealthier would you be one year from now if you exchange $100,000 (U.S.) into Hong Kong Dollars today at an indirect rate of HK$7.8/$, earn 7% on your Hong Kong investment, and exchange back at a rate of HK$8.0/$, as compared to investing in the U.S. at 4.0%?
