Franca makes $22.30 per hour working as a full-time receptionist. She works 7 hours per day, 35 hours per week with no overtime, and is given 7 hours automatically for any statutory holidays that occur. She is paid weekly. She has been doing extra duties since February 5, 20xx so her boss has decided she deserves a raise. The raise will be retroactive to Feb 5, 20xx, and will cover the end of the last pay period that has been processed (which was July 6, 20xx). Her new rate of pay will be $25.50.
