You have 250,000 in an ira at the time you retire. you have the option of investing this money in two funds. fund a pays 1.2% annually and fund b pays 6.2% annually. how should you divide your money between fund a and fund b to produce and annual interest income of $8,000?

Let x be the amount of money, you fund in Fund A and y be the amount of mone yyou fund in Fund B.

1. You have 250,000 In an IRA at the time you retire and want to invest this money into Funds A and B, then

2. Fund A pays 1.2% (as a decimal 1.2% is 0.012) annually, then is annual interest income in Fund A.

Fund B pays 6.2% (as a decimal 6.2% is 0.062) annually, then is annual interest income in Fund B.

Since Fund A and Fund B produce an annual interest income of $8,000, then

3. Solve the system of equations:

Express x from first equation and substitute it into the second equation

Multiply this equation by 1000:

Then

you have to fund $150,000 in Fund A and $100,000 in Fund B.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
