Answer:
Number of students= 820.64 = 821
Step-by-step explanation:
Giving the following information:
Current attendance= 950 students
Number of periods= 3 years
Decrease rate= 5%
<u>To calculate the number of students in attendance in 3 years, we need to use the following formula:</u>
Number of students= current attendance*(1+decrease rate)^(-n)
Number of students= 950*(1.05^-3)
Number of students= 820.64 = 821
Answer:75 children
Step-by-step explanation: Let the number of children will be x, so the number of adults will be 215-x
Making equation: 3x+5(215-x)=925
3x+1075-5x=925
-2x=925-1075
-2x=-150
x=75
