Answer:
Step-by-step explanation:
In a is the initial value and b is the growth/decay rate. Our initial population was 25,000 so a = 25,000. Our rate of decay is 4% or, as a decimal, .04. BUT if the rate of decay is .04, then .96 remains. b = .96
C. 120 students
10 + 15 + 20 +30 = 75%
100 - 75 = 25%
25% chose football which is 100 students
30% chose swimming
setup proportion:
25/100 = 30/x
25x = 100(30)
25x = 3000
x = 120

10=7-m
10-7=-m
3=-m
m=-3
