Let the profit at the first year be X
3x=114000
Solve for x by dividing each side by 3
3x/3=114000/3
X=38,000
So the profit was 38000
Cost = (3,500) * (1.04)^years
Cost = (3,500) * (1.04)^4

Formula
------------------------------------------------------
Area of circle = πr²
------------------------------------------------------
Find Radius
------------------------------------------------------
200.96 = πr²
r² = 200.96 ÷ π
r² = 63.97
r = √63.97
r = 8 km (nearest hundredth)
------------------------------------------------------
Formula
------------------------------------------------------
Circumference = πD
------------------------------------------------------
Find Diameter
------------------------------------------------------
Diameter = Radius x 2
Diameter = 8 x 2
Diameter = 16 km
------------------------------------------------------
Find Circumference
------------------------------------------------------
Circumference = πD
Circumference = π (16)
Circumference = 25.13 km
------------------------------------------------------
Answer: Circumference = 25.13km

2x-1=3/4x+9
2x-3/4x=9+1
1.25x=10
X= 8
