Answer:

40 black ink cartridges and 19 colored ink cartridges

Step-by-step explanation:

Let $b$ represent the number of black printer ink cartridges sold. Let $c$ represent the number of color printer ink cartridges sold.

Set up a system of equations:

$\displaystyle\\\begin{cases}b+c=59\\17.99b+20.99c=1,118.41\end{cases}$

$b+c=59\implies b=59-c$

Substitute:

$\displaystyle\\17.99(59-c)+20.99c=1,118.41\\\implies c=\boxed{19}$

$\implies b+19=59\implies b=\boxed{40}$

⇒ 40 black ink cartridges, 19 colored ink cartridges (ans)
