Answer:
There are a total of 78
Step-by-step explanation:
Here we are to calculate the number of 7th grade students at Willow middle school given the information in the question.
Now, to calculate the number of people that attended the party, we add those that have left to those still remaining = 36 + 34 = 70 students
Now this number equals 90% of students
Thus let’s say the total number of students is x
90/100 * x = 70
90x = 100 * 70
90x = 7000
x = 7000/90
x = 77.77 which is approximately 78 students
