Let 't' = number of hours Renee will have to work.
Concept: The average rate Renee gets paid is equal to the total wages earned divided by the total number of hours worked.
Rene earns$40 per hour for the first 40 hours, so she makes40×40= $1,600 in the first 40 hours. She also earns$80 for every hour after 40 hours, for additional pay of$80(t – 40). Therefore, her total pay can be calculated as:
So,\frac{1600+80(t−40)}{t}=60
Or, 1600+80t-3200=60t
Or, 20t=1600
or, t=80 hours
