Answer:
Amount in savings account = $24,000
amount put into time deposit account = $11,000
amount put into bond account = $7,000
Step-by-step explanation:
Let x be amount put into savings account, y be amount put into time deposit account and z be amount put into bond account.
Thus;
0.05x + 0.07y + 0.09z = 2600 - - (eq1)
Also,
x + y + z = 42,000 - - - (eq2)
Now,we are told she invested 6000 more in the savings account than the other 2 combined. Thus;
x = 6000 + y + z
So,
x - y - z = 6000 - - - (eq3)
Solving the 3 equations simultaneously gives;
x = $24,000 ; y = $11,000 ; z = $7,000
