Answer:
Step-by-step explanation:
Zinnia works 40 hours and earns $13 for each of those 40 hours, putting her at 40 * 13 = $520.
Then she works 9 hours over and earns$20 for each of those 9 hours, putting her at 9 * $20 = $180.
Adding those 2 together gives Zinnia a grand total of $700 in that week.
