Question

solve for c.
1 > \frac{c - 16}{4} \geq -1
write your answer as a compound inequality with integers.

Explanation:

Step1: Multiply each part by 4

$1\times4>\frac{c - 16}{4}\times4\geq-1\times4$
$4>c - 16\geq-4$

Step2: Add 16 to each part

$4 + 16>c-16 + 16\geq-4 + 16$
$20>c\geq12$

Answer:

$12\leq c<20$
