Answer:
£246
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.
