Answer:
The answer to your question is $56
Step-by-step explanation:
Data
Payment before noon = $11.20
Payment after noon = $11.20/2
Time from 9:00 to 16:00
Process
1.- Calculate the hours worked before noon and the hours worked after noon.
Before noon = 12:00 - 9 = 3 hours
After noon = 16:00 - 12:00 = 4 hours
2.- Calculate the payment
Payment = (3 x 11.2) + (4 x 11.2/2)
= 33.6 + 22.4
= $56
