It costs $315 to book a DJ for 3 hours. It costs $525 to book the same DJ for 5 hours. Write an equation that represents the cost y in dollars of booking a DJ for x hours.

  y = 105x

Step-by-step explanation:

$315 ÷ 3 = $105 per hour

$525 ÷ 5 = $105 per hour

Constant of Proportionality is $105 in both cases.

y = kx

y = 105x

$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
