You place $25,000 in a savings account paying an annual compound interest of 8 percent for 3 years and then move it into a savings account that pays 10 percent interest compounded annually. What is the original balance worth at the end of six years?

I'm overthinking this - would the original balance be the difference or totally amount including the initial $25,000 down payment? I listed the total amounts below:

Difference $16,916.92

OR

FV Total $41,916.92
