Is the algebra, if so what type?
3d+8=2d-17
-2d -2d
__________
d+8=-17
-8 -8
__________
d=-25
Answer:
x=0.5
Step-by-step explanation:
2x+y= -2
and
4x+y= -8 so...
2x+y= -2 = 4x+y= -8
2x+4x= 6x
y+y=2y
-2+-8= -10
6x+2y= -10
2y- -10= 12
6x=12
6/12=0.5
x=0.5
The value of the bike at any year n is calculated through the equation,
At = (A1) x (1 - r)^n
Substituting the known values,
At = ($500) x (1 - 0.25)^5 = $118.65
Thus, the bike would cost only $118.65 after 5 years and the answer is letter B.
