Jessica is making $300 less than four times what she was making when she started working. Let a represent her starting salary. Write an expression showing 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
