(a) A house in Country X was built and sold for $680,360 in 1995. It is currently selling for $4,250,880 in 2022. What was the annual increase in the value of this house?

(b) MARS Bank pays 10 percent simple interest on its saving account balances, whereas VANS Bank pays 10 percent interest compounded annually. You deposit the same amount of $X in each bank. At the end of seven years, the difference between account balance of VANS bank and MARS bank is $3,309.03. Find the $X.

(c) Jenny believes that the house price in country X will be in decline due to massive supply of new houses. Today is her 20th birthday, she is planning to buy her first house by making 120 monthly deposits of $12,500 into a saving account at IU Bank that pays 16 percent interest compounded monthly. If her first deposit will be made one month from today, how much will Jenny's saving account balance on her 30th birthday?
