The given amount of annual interest is earned from a total of $11,000 invested in two funds paying simple interest. write and solve a system of equations to find the amount invested at each given rate.

annual interest: $400

invested at 3% and 4%

$4000 was invested into 3% interest and $7000 was invested into 4% interest.

Step-by-step explanation:

let n be amount invested into fund1 at 3%

let p be amount invested into fund2 at 4%

n + p = 11,000    <=equation for initial investments

0.03n + 0.04p = 400   <=equation for interest earned

Rearrange n+p=11,000.

n = 11000 - p         Substitute this equation into the other for "n"

0.03n + 0.04p = 400

0.03(11000 -p) + 0.04p = 400

330 - 0.03p + 0.04p = 400

330 + 0.01p = 400

0.01p = 70

p = 7000

Substitute p=7000 into an equation to find n

n + p = 11000

7000 + n = 11000

n = 4000

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
