The total number of chairs required is 98.
Question 8:
Working hours of cinema per month= 120 hours
total hours worked by Leanne in September = 138 hours
per hour pay = £7
over time pay per hour = £9
how much did she get paid in September = ?
⇒138 hours - 120 hours = 18 hours
it means that out of 138 total hours she has worked, she worked overtime for 18 hours.
⇒120 hours × £7 = £840
she got paid £840 for working 120 hours
⇒18 hours × £9 = £162
She got paid £162 for working 18 hours additional
⇒£840 + £162 = £1002
Therefore,
Leanne is paid £1002 for working £138 in September.
