Let f=amount invested at 4% and e=amount invested at 8%
0.04f+.08e=800
However, e=2f so the above equation becomes:
0.04f+0.08(2f)=800
0.04f+0.16f=800
0.2f=800
f=$4000, since e=2f
e=$8000
So Susan invested $4000 at 4% and $8000 at 8%.
Here is the answer! I hope it’s helpful
Answer:
M = (3, 3.25)
Step-by-step explanation:
First, using the internal selection formula
Given
m:n = 3:5
(x1,y1) =(0,1)
(x2,y2) =(8,7)
![M={[(mx2+nx1)/(m+n)],[(my2+ny1)/(m+n)]}](https://tex.z-dn.net/?f=M%3D%7B%5B%28mx2%2Bnx1%29%2F%28m%2Bn%29%5D%2C%5B%28my2%2Bny1%29%2F%28m%2Bn%29%5D%7D)
M = (3, 3.25)
2.
M is the point on XY that is 3/8 of the way from X to Y.
x-coordinate of M = 0 + (3/8)(8) = 0 + 3 = 3
y-coordinate of M = 1 + (3/8)(6) = 1 + 2.25 = 3.25
So, M = (3, 3.25)
or (3, 3 1/4)
Answer:
C
Step-by-step explanation:
Answer:
A. 6n+6.25 = 48.25
Step-by-step explanation:
$48.25 Money to spend
Each class costs $6 plus
one time $6.25
N= # of classes
So
6= slope rise over run
48.25 is total
6.25 is the y-intercept First time payment
u only pay once
48.25=6n+6.25
