Daisy works at an ice-cream parlor. She is paid $10 per hour for the first 8 hours she works in a day. For every extra hour she works, she is paid 1.5 times her hourly wage. If Daisy works for x hours in a day, and x is greater than 8, the expression giving her net earnings for the day is . If Daisy works 13 hours, she will be paid .

Mercury:

"she is paid $10/hr for the first 8 hours" ---> regular pay is simply 8*10 = $80 "for every extra hour she works, she is paid 1.5 times her hourly wage. if Daisy works for x hours in a day, and x is greater than 8" since the 1.5x bonus only applies to hours after the first 8, the hours that qualify for overtime can be expressed as (x-8). basically, the total number of hours (x) minus the 8 hours that only get regular pay. applying the 1.5* hourly wage bonus, this becomes 1.5*10*(x-8) for the overtime pay now, for the net earnings expression, simply add up the regular pay and overtime pay expressions to calculate how much money Daisy will earn for 13 hours of work, simply plug in x = 13 into the expression from the previous step.
