1) If your salary of 40000 increases by 5% next year, increases by 2% the following year, and decreases by 5% the year after that, what will your annual salary be in three years (to the nearest dollar)

2) If you have two mugs of hot chocolate, one that is 32% chocolate and the other 20% chocolate, how much of each would you need to make one cup that is 25% chocolate?

Thanks a million!!!
