Question

Solve each of the inequalities and express the solution sets in interval notation. Match each of the inequalities with the interval to obtain a true statement.
-$( - \infty , 30 ]$ 
A) $0.01 x + 0.09 ( 400 - x ) \geq 33.6$ 
B) $0.06 x + 0.9 ( x + 100 ) > 858$ 
C) $x \geq 3.18 + 0.47 x$

Quizplus · Accepted Answer

To solve inequality A, simplify and solve for x:  $0.01x + 36 - 0.09x \geq 33.6$  $-0.08x \geq -2.4$  $x \leq 30$  The solution in interval notation is $(-\infty, 30]$.
