Answer: any amount from 0 to 90000 USD
Step-by-step explanation:
x USD will be paid for 15% bonds that makes x*0.15 USD /per year
So 90000-x will be paid for 7% bonds , that makes (90000-x)*0.07 USD/per year= 6300-0.07x USD / per year.
So the total amount the woman gets from both investments yearly should be not less than 3000 USD/per year
Otherwise
0.15*x+6300-0.07*x>=3000
0.08*x+6300>=3000
The inequation is correct for any x>=0
The woman will be able invest in CD any amount from 0 to 90000 USD.
If we suppose that investments in CD more safe we'd recommend to the lady to invest all money to CD.
Note: Since the interest rate is not mentioned in the question, I'll just assume it is 8% to be able to do the calculations. You can replace this 8% with the interest rate in your question.
The equation that we will use to calculate the interest is:
I = P*r*t where:
I is the interest that we need to calculate
P is the principle amount of money = <span> $12,400
r is the interest rate = 8% = 0.08
t is the time of the loan = 29 months = 29/12 = 2.41667 years
Substitute with the givens in the above mentioned equation to get the interest (I) as follows:
I = 12,400 * 0.08 * 2.41667 = $2397.334</span>
