4a - 300 represents how much Jessica is making now
Solution:
Given that,
Let "a" represent her starting salary
Jessica is making $300 less than four times what she was making when she started working
Therefore,
Jessica salary now = $300 less than four times the starting salary
Jessia salary now = 4 times the starting salary - 300
Jessia salary now = 4a - 300
Thus the above expression denotes how much Jessica is making now
