We are asked to solve the equation $\frac{c}{4} + 13 = -8$ for the variable $c$.

1. Problem Description

We are asked to solve the equation $\frac{c}{4} + 13 = -8$ for the variable $c$.

2. Solution Steps

We want to isolate $c$ on one side of the equation.

First, subtract $13$ from both sides of the equation:

$\frac{c}{4} + 13 - 13 = -8 - 13$

$\frac{c}{4} = -21$

Next, multiply both sides of the equation by $4$:

$4 \cdot \frac{c}{4} = 4 \cdot (-21)$

$c = -84$

3. Final Answer

$c = -84$
