Step-by-step explanation:

45 students

Total number of students= 45

number of absentees= 5

number of present= 40

number of the students who failed to submit their homeworks= 30%

the 30% of 40 is 12

40*0.30 = 12 students

the 70% of 40 is 28

40*0.70 = 28 students

there are 28 students who submitted their homework.
