Question: Find the answer to the math problem: Eliza's rate per hour for the first 40 hours she works each week is $10. She also receives an overtime pay of 1.2 times her regular hourly rate. If Eliza worked for 45 hours this week, how much are her earnings for this week?
Answer: 
Eliza is entitled to 45 -40 = 5 hours overtime pay.
Her hourly rate for the overtime pay is $10 x 1.2 = $12.
So, Eliza will receive $12 x 5 =$60 for overtime pay.
Her regular weekly earning is $10 x 40 = $400.
Thus, Eliza will receive a total of $400 + $60 = $460 for this week's work.
