<span>Let C denote the number of candidates they interview and E the number of employees they train.
</span>
<span>If it takes 20 hours and $400 to interview a candidate, then it takes 20C hours and $400C to interview C candidates.
</span>

</span>
Company <span>wants to spend at most 470 hours, then
.
</span>
<span>You obtain the system of two inequalities:
</span>
