Let the number of tie-dyed T-shirts = x

The man sold 4 times as many tie-dyed T-shirts as silk-screened shirts.

So, the number of silk-screened shirts = 4x

He sold 180 shirts altogether

So,

$\begin{gathered} x+4x=180 \\ 5x=180 \\ \\ x=\frac{180}{5}=36 \end{gathered}$

So, the number of tie-dyed shirts = 36
