Final answer:
The amount invested in CDs is $52,497.50, the amount invested in bonds is $107,497.50, and the amount invested in stocks is $5.
Step-by-step explanation:
Let's assume the amount invested in CDs is C. Since the amount invested in bonds is $55,000 more than in CDs, the amount invested in bonds is C + $55,000. The amount invested in stocks is given as $5. The total amount invested is the sum of these three amounts: C + (C + $55,000) + $5. We can set up the equation:
C + (C + $55,000) + $5 = $160,000
Simplifying the equation gives us: 2C + $55,005 = $160,000. Substracting $55,005 from both sides gives us 2C = $104,995. Dividing both sides by 2 gives us C = $52,497.50.
So, the amount invested in CDs is $52,497.50, the amount invested in bonds is $52,497.50 + $55,000 = $107,497.50, and the amount invested in stocks is $5.
