S = 10 + r
s + r = 100
Adding equations,
2s +r = 110 + r
2s = 110
s = 55
r = 45
Answer:
Part 1) The total square footage of the fence is 
Part 2) 
Step-by-step explanation:
Part 1) what is the total square footage of the fence ?
we know that
The area of the fence is equal to

substitute the values

Part 2) How much will Jake get paid
Using proportion

G(-2) = 8(-2) -2 = -16 - 2 = -18
g(4) = 8*(4) - 2 = 32 - 2 = 30
as you can see 30 is greater than -18 so the answer is C
