Answer:

Step-by-step explanation:
step 1
Find the equation of the solid line
Find the slope
we have
(0,0.2) and (3,2.2)

The y intercept b is equal to

so
the equation of the solid line in slope intercept form is equal to

step 2
Find the equation of the inequality
we know that
The solution of the inequality is the shaded area below the solid line
therefore

Our trick here is to think that a fraction in %
land is the same as the correspondent in "number" land; so we can write:
100%
90%
= 120x
Where X is the correspondent of 90% in numbers.
Rearranging: x = 120⋅
90% 100% =108
