Answer: Your weekly cash flow for the full-time job would be $480 while the cash flow for the part-time job is $150.
Explanation:
If you work 20 hours for $15, that's $300 by the end of the week. However, because of the extra time for entertainment, that $150 takes half of your earnings. 15 x 20 = 300 - 150 = 150. Because you don't have time for entertainment with the full-time job, you only have the $480.
