Answer:
76800 cases
Step-by-step explanation:
The number of cases of new infectious diseases reported last year= 150 cases
Number of cases are going to be double every year
Number of the cases in next or first year=150+150=300
Number of the cases in next or second year=300+300=600
Number of the cases in next or third year=600+600=1200
Number of the cases in next or fourth year=1200+1200=2400
Number of the cases in next or fifth year=2400+2400=4800
Number of the cases in next or sixth year=4800+4800=9600
Number of the cases in next or seventh year=9600+9600=19200
Number of the cases in next or eight year=19200+19200=38400
Number of the cases in next or ninth year=38400+38400=76800
Hence , the total number of cases are 76800 cases
