Sheila earned $320 for 8 hours of work. she worked for 6 days. how much does she
earn each hour?

I got 40 an hour.

Step-by-step explanation:

It matters little how many days she worked - she could have worked for 20 days, but if her hours all add up to 8 - then you simply divide the amount she earned by the number of hours (exluding taxes ;)

Still, if she worked for 6 days then she worked for 1.3 hours each day - or 1 and roughly 20 minutes (specifically 18 minutes).

320/8 = 40 so ... 40/h.
