A couple thinking about retirement decide to put aside $3,400 each year in a savings plan that earns 7% interest. In 10 years they will receive a gift of $14,000 that also can be invested.

How much money will they have accumulated 30 years from now?

If their goal is to retire with $840,000 of savings, how much extra do they need to save every year?

Note: Do not round intermediate calculations. Round your answer to 2 decimal places.
