Write a rule for the linear function in the table.
a. f(x) = –4x
b. f(x) = x + 16
c. f(x) = 4x
d. f(x) = -1/4x

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

$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
