C. A four-sided field needs to be fenced. Two sides are each b feet long. The length of the third side is 3 feet less than 7 times the fourth side. If the length of the fourth side is represented by m, write an algebraic expression that represents the length of the fencing needed.

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

not sure but it may be b, as i said i'm not sure.
