See the entire solution process below:

Multiply each side of the inequality by $color(red)(5)$ to solve for $c$ while keeping the inequality balanced:

$color(red)(5) xx 4 < color(red)(5) xx c/5$

$20 < cancel(color(red)(5)) xx c/color(red)(cancel(color(black)(5)))$

$20 < c$

To solve in terms of $c$ we must reverse or "flip" the inequality:

$c > 20$
