Jan Quint earns $11.00 an hour at her job and is entitled to time-and-a-half for overtime, and double time on holidays. Last week she worked 40 hours of regular time, 9 hours of overtime, and 12 hours of holiday time. $852.50 she earn last week.



11 + (11/2) = 11 + 5.5 = $16.50.
= 11 x 2 = $22.00.
40 hours regular time = 40 x 11 = $440. 9 hours overtime = 9 x 16.50 = $148.50.
12 hours holiday time = 12 x 22 = $264. 440 + 148.50 + 264 = $852.50.
