1. mary stevens earns $6 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, 61/2 hours of overtime, and 8 hours of holiday time. how much did she earn?

I believe the answer is $375
if you do 6×40 you get $240
then 6×8 is 48 but you get double so it is $96
then you work overtime so 6×6 is $36 but then you only work half of an hour which is $3. then if you add 240+ 96+36+3 you get $375. i think this is right
