At Ali after 5 drinks one can get another for free. while at Bob's there is 20% off the total.

Hence first find the number of days in may = 31

Now make a series that can make computation easier. At Ali 5, D, 5, D, 5, D, 5, D, 5, D, 1
Hence cost at ali would be \(2.25*5*5 + 1*2.25 = 58.5\)

At bob \(2.25*31 = 69.75* 0.8 = 55.8\)
