Let x be the amount invested in CDs.
Then, the amount invested in bonds is x + $10,000.
The amount invested in stocks is $145,000 - (x + x + $10,000) = $125,000 - 2x - $10,000 = $115,000 - 2x.
The annual income from the stocks is 6.7% of ($115,000 - 2x), which is 0.067($115,000 - 2x) = $7715 - 0.134x.
The annual income from the bonds is 2.5% of (x + $10,000), which is 0.025(x + $10,000) = $250 + 0.025x.
The annual income from the CDs is 5.75% of x, which is 0.0575x.
The total annual income is $7715 - 0.134x + $250 + 0.025x + 0.0575x = $6977.5.
Simplifying and solving for x, we get:
0.9485x + $7465 = $6977.5
0.9485x = $-487.5
x = $513.56 (rounded to the nearest penny)
Therefore, Maricopa Success invested $115,000 - 2x = $113,972.88 in stocks, $10,000 + x = $10,513.56 in bonds, and x = $513.56 in CDs.
