A couple deposits $2,500 now and another $5,000 four years from now, then withdrew $3,000 six years from now (for a very nice UHD 4K projector and home theater equipment purchase), and deposits $4,000 seven years from now. The interest rate started at 15% per year compounded weekly, but at the end of the 6th year, the interest rate lowered to 10% per year compounded monthly. How much money will they have in their account if it was withdrawn 12 years from now based on the above scenario? (a) Draw the correct fully labeled CFD for the scenario above. (E.C. 1] (b) Only write the equation for this scenario...do not solve this! [E.C. 2]
