$\left\{\begin{array}{l}12x+9.50y\ge 220\\ \\x+y\le 20\end{array}\right.$

Step-by-step explanation:

Let x be the number of hours Jackie tutors and y is the number of hours she works as a lifeguard.

She can work no more than 20 hours per week, thus

$x+y\le 20$

Jackie works as a tutor, which pays $12 per hour, then she earns $12x in x hours.

She works as a lifeguard, which pays $9.50 per hour, then she earns $9.50y in y hours.

Jackie wants to earn at least $220 per week, so

$12x+9.50y\ge 220$

So, you get the system of two inequalities:

$\left\{\begin{array}{l}12x+9.50y\ge 220\\ \\x+y\le 20\end{array}\right.$
