Answer:
103 chairs
Step-by-step explanation:
cost = fee + cost per chair * number of chairs
410 = 100 + 3*c
Subtract 100 from each side
410-100 = 100+3c-100
310 = 3c
Divide by 3
310/3 = 3c/3
103.3=c
We cannot rent part of a chair so we round down
103 chairs

It would be helpful to see the actual choices, but let me try to answer anyway:
(1) blue area:
y>=4*x+1
read area
y<-3
(2) blue:
y>3*x-3
red:
y <= 0.5*x + 2
Answer:
f = 4d -400
Step-by-step explanation:
First, let's make some variables.
f = size of Falls Lake
d = size of Lake Drummond
d = (1/4)*f + 100
We can now rearrange the equation to find the size of Falls Lake.
d - 100 = (1/4)*f
4d - 400 = f
f = 4d - 400
