x = 16/y

or

y =16/x

Step-by-step explanation:

31=xy+15

subtract 15 from both sides of the equation:

xy = 16

x = 16/y

or

y =16/x

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
