Multiply 15000 by 0.8³ to get $7680
You get 0.8 because 100% minus 20% is 80% so you turn that into 0.8 and its 0.8³ because theres 3 years. Hope that made sense!
Option D:
k = –2
Solution:
Let y = f(x).
<u>Direct variation:</u>
A relationship between two variables in which one is a constant multiple of the other.
<em>y varies constantly means that y = kx.</em>
The constant .
Substitute x = –1 and y = 2 from the table.
Substitute x = 2 and y = –4 from the table.
Substitute x = 5 and y = –10 from the table.
Therefore k = –2.
Option D is the correct answer.
