Answer:
$218
Step-by-step explanation:
$100 times 100% = $200
9% of 200 = 200X.09 = 18
200 + 18 = 218
Hello,
Line 1 is passing through (-4,3), (-2,7) has a slope of (3-7)/(-4+2)=2
Line 2 is passing through (2,9), (4,1) has a slope of (9-1)/(2-4)=-4
One other way:
y=9-1/2 x²
y'=-x
gradient 1=-(-2)=2 for point (-2,7)
gradient 2=-(4)=-4 for point(4,1)
So first you do 2000x+300x=y Then I found that it would be 7 people because it says you have to at LEAST have 14000 and with 7 people you get 16100
