Final answer:
To calculate the cost of the fence, we need to determine the total number of feet of fencing required and use a proportion to find the cost.
Step-by-step explanation:
To calculate the cost of the fence, we need to determine the total number of feet of fencing required. Given that for every 3 feet of fencing the cost is $27, we can set up a proportion:
x feet / $27 = total feet / $27
Since the total feet of fencing is not given, we can assign it a variable, such as 't'. The equation becomes:
x / $27 = t / $27
To solve for x, we can multiply both sides of the equation by $27:
x = t
Therefore, the cost of the fencing, x, is equal to the total number of feet of fencing required, t, multiplied by the cost per foot, which is $27.
