Question 280222: A credit union offers 5.5% simple interest on a ceritificate of deposit (CD) and 3.5% simple interest on a savings account. If Mr. Sorkin invested $200 more in the CD than in the savings account, and the total interest after the first year was $245, how much was invested in each account?

I came up with 0.055(x + 200) + 0.035y=645 & (x + 200) + y = 1200, assuming that 1000 is needed to open a CD...

Do we presume that the intial invested in the CD is 1000 plus 200? Some people don't even know that most CD's is a minimum of a 1000 to open the account. I don't think so, let me know what you think when possible.

Thanks,
Alex Vargas
