His younger sister; Jenniffer, will go to college in 5 years. She just told her parents that she plans to enter the University of San Francisco, which will cost $ 30,000 per year for 4 years (costs will apply at the end of each year). Anticipating Jenniffer's plans, her parents started investing $ 3,000 a year for 5 years and will continue to do so for 5 more years. How much more will her parents have to invest each of the next 5 years to fund Jenneffer's education? Use 10% as the stated interest rate for this whole problem (be it discounted or compounding). Round to whole numbers.
