Answer:

42%

Step-by-step explanation:

there were 89 total students

we know its less than 50 percent because 50 percent is 44.5

we can use the process of elimination to find that it is 42

the multiplier for 42% is .42 (move the decimal over 2 to the left)

when you multiply 89(.42) you get 37 (37% of students)
