Answer:
[-5, 2]
Step-by-step explanation:
We have to find the interval for which f(x) <= 0, the interval is [-5, 2].
The least number of brownies that he must have sold was 2.
$0.18 x 2 = $0.36
$0.36 - $0.36 = $0.00
Option D is a linear equation, so it represents a direct linear variation.
Hope this helps!
