Answer:
Wednesday
Step-by-step explanation:
On Sunday, total number of books are 480
Half of them gets sold by the end of the day=480/2=240
And 16 are added at the end of the day=240+16=256
On Monday, total number of books are 256
Half of them gets sold by the end of the day=256/2=128
And 16 are added at the end of the day=128+16=144
On Tuesday, total number of books are 144
Half of them gets sold by the end of the day=144/2=72
And 16 are added at the end of the day=72+16=88
On Wednesday,total number of books are 88
Half of them gets sold by the end of the day=88/2=44
Therefore; On Wednesday the warning will be given.
