James works from 2pm until 8:30pm on both Thursday and Friday. He is paid £12 per hour. On Saturday, he is paid 1 and 1/2 times his hourly pay. He works for 5 hours on Saturday. Calculate how much James earns in TOTAL for these three days.

9514 1404 393

  £246

Step-by-step explanation:

James works 8:30 -2:00 = 6: 30 hours on Thursday and Friday, for a total of 2×6:30 = 13:00 hours.

James works 5 hours on Saturday, but gets paid for 5×(1 1/2) = 7.5 hours. Then for the three days, he gets paid for 13 +7.5 = 20.5 hours.

James's total pay for the three days is ...

  (20.5 h)(£12/h) = £246 . . . . pay for 3 days

Additional comment

The associative property of multiplication says you can associate the factor 1 1/2 either with the hours or the pay:

  (5 h)((1 1/2)(£12/h)) = ((5 h)(1 1/2))(£12 /h)

The computation involving "time and a half" often calculates the pay separately for overtime hours. I sometimes find it easier to calculate the pay for overtime by increasing the hours, rather than the pay.

what i would say the best answer is a. 40.5
