Different wayof working

Was trying to see if this could be worked algebraically

May Earnings

Total earnings assume = X

Mrs Lee = .6X

Rest = X-.6X

June Earnings

Mrs Lee = .6X+ .6X/5 = 3.6X/5

Rest = X-.6X

Total Earnings in June = 3.6X/5 + X-.6X = 5.6X/5

Therefore Earning in June = 1.12 X

Assuming X= 100 , Earnings in June = 112 and Mrs lees earnings = 72

Earning % in June for Mrs lee = 72*100/112 = 64 approx

I prefer the other way of assuming it be 100 to start with . It is faster and simpler.
