lilg this actually is not correct

122 - 82 = 40

the answer i gave was correct but it was just i wrote it as per hour

we do 122 - 82 because 122 is 11 hours and 82 is 7 hours

so if we do 

11 - 7 hours = 4 hours which is what we are trying to work out

so we just minus the two costs which give us $40

sorry but the equation i showed was correct before n i deleted it :(
