Here's the rest of the math questions 17 and 18
Lelu [443]

17. On average, Nestor works 7.5 hours of overtime in 4 weeks, so works an average of 7.5/4 = 1.875 overtime hours per week.

On average, each week Nestor gets paid for 7.5×5 + 2×1.875 = 41.25 hours, so is paid*

... (41.25 h)×($7.42/h) = $306.075

Each week Rita gets paid for 8×5 + 1.5×3 = 44.5 hours, so is paid

... (44.5 h)×($7.64/h) = $339.98

Their combined earning for a week are $306.075 + 339.98 = $646.055, so over a period of 12 weeks, they are paid a total of

... (12 weeks)×($646.055/week) = $7,752.66

18. Assuming Robin is paid time and a half for overtime, she was paid for

... 40 + 1.5×6 = 49 . . . hours

Then her hourly pay was ($392/week)/(49 hours/week) = $8.00 per hour

___

* The half-cent that shows up in Nestor's average weekly pay does not actually show up in Nestor's paycheck. Here, it is an artifact of dividing his monthly hour total by 4 to get a weekly average. Nestor's total pay for any given week is whole number of cents.
