I dont get this question at all!
Write a system of equations to solve the following problem. Show the solution neatly and clearly, check yout answers.
Andrea has invested part of $6000 in Pine City Municipal Bonds which pay 6% annual interest. She has invested the rest of the $6000 in Oak City Municipal Bonds which pay 8% annual interest. If her total income from these two investments is $460, how much did she invest in each?
AGHHH I hate math, please I really need help!
x = part invested in pine City
y = part invested in Oak City
x+y = 6000
0.06x = interest in pine City
0.08y = interest in Oak City,
so
0.06x + 0.08y = 460
Your system is:
x + y = 6000
0.06x + 0.08y = 460
solve from there on your own... you'll need the skill for the test you will have. 😊
Thanks a bunch... but its not gunna be on a test we get weekly problem sets that have nothing to do with our unit... but I know what u mean
If you want to use one variable:
at 6%
(X)
at 8%
6000 - X
.06X +.08(6000-X)=460
.06X +480 -.08X=460
-.02X=-20
.02X=20
X=1000
EDIT: Argh, late.
EDIT2: 15ooth post
SO 1000 was into Pine City and 5000 was in Oak city...
hooray.
I owe u 1
Yeah, I checked it too. If you use two variables:
x + y = 6000
0.06x + 0.08y = 460
Y=6000-X
Substitute the above equation in for Y and you get:
.06X+.08(6000-X)=460
X=1000
Plug in the value in:
X+Y=6000
1000+Y=6000
Y=5000
I'm in Algebra III honors, and I'm in tenth grade, but I had problems like these back in 8th grade.
Hmm. I'm only in 8th grade and they gave me problems like that before. I forgot how to do them though. I hate math.
HAHAH Im in 12th grade...
lol Theres alot in math I like and understand I just HATE word problems...
who the fuck cares what some bitch is wasting her money on!
Wow! I'm having a test on system of equations, slopes, intercepts, .... ect ..... and I'm only 12 .....

I'm in Algebra 3.46? 😃
Well it's funny to me.
They should change the name of the Algebra 3 class to Algebra pi.
