Answer:
£105.00
Step-by-step explanation:
£7/hour
Time and a quarter: (£7/hour)*(1 + 1/4) = (£8.75/hour)
Time and three quarters: (£7/hour)*(1+ 3/4) = (£12.25/hour)
Saturday for 5 hours: (£8.75/hour)*(5 hours) = £43.75
Sunday for 5 hours: (£12.25/hour)*(5 hours) = £61.25
Sum of £43.75 + £61.25 = £105.00
