 Hey, this is Josh at Parkside, and help me out here. My seventh grade son asks me, when will I ever use math in my life? Sound familiar, parents? Well, here's a good example. Our Casasa cash checking account rate used to be 2.5%, and now it's 4% APY. So, if you look at that rate, and some terms and conditions apply, that's the difference between making about $30 a month and making $50 a month. How do you like them apples?
