Mrs. brown is $3.00 per hour for a regular week of 40 hours. caluate her wage for a regular week overtime is paid at time and a half how much is paid for one hour of overtime. calculate her wage for a week went she work 44 hours

If Mrs. Brown earns $3.00 x 40 then she makes $120 for her 40 hours of work. Then she is paid 4 hours of overtime which is worth 1.5 times $3.00 = $4.50 
That means that you would take the $120 and add on the overtime $4.50 x 4 = $18, therefore she makes $138 in her 44 hour week.
