• In order to keep the amount invested in the growth fund to a minimum, nothing can be invested in CDs, as they have the lowest return. Thus you have g + b = 50,000 0.146g + 0.087b = 5,000 0.087g + 0.087b = 4,350 0.059g = 650 g = $11,016.95 b =…

• b = c = d = f = g > a > e if the acceleration at a is just before the ball is released. a = b = c = d = f = g > e if the acceleration at a is when or just after the ball is released.
