Why can a subtraction problem be rewritten as an addition problem without changing the outcome? give a real-world scenario where this might be modeled.

Because the way subtraction and addition work are as sums. You are simply gathering together different variables. If we put together +5 and negative 2, we get +3. However, it is much simpler to say 5-2=3. Hope that helps!

Answer:

$4034.40

step-by-step explanation:

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
