Step-by-step explanation:
First you must find out what the initial payment would have been, My way of doing it was simply multiplying 37 by 11.5
I then get 425.5, then to find out the amount for the .5 (half hour)simply divide 11.5,the answer is then £5.75,....now we add £425.5 + £5.75= £431.25
Now... we need to deduct her “deductions” lol which was £116.30 so
£431.25-£116.30=£314.95
So her payment was £314.95
Really hoped that helped have a wonderful day
