A total of $8000 is invested in 2 funds paying 4% and 5% annual interest. The combined annual interest is $350. How much of the $8000 is invested in each fund? Please show work!!

$3000.

Step-by-step explanation:

$Po invested at 4%.

$(8000-Po) invested at 5%

Po*0.04*1 + (8000-Po)*0.05*1 = 350.

0.04Po + 400 - 0.05Po = 350,

Po = $5000.

8000-Po = 8000-5000 = $3000.

Hope this helps :)

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
