7/100 = x/$23,845

Here, "x" represents the amount we want to find, which is 7% of the total cost.

To solve the proportion, we can cross-multiply:

100x = 7 * $23,845

Next, we can solve for "x" by dividing both sides of the equation by 100:

x = (7 * $23,845) / 100

Now, we can calculate the value of "x" by multiplying 7 with $23,845 and then dividing the result by 100.

Let's do the math:

x = ($166,915) / 100
x = $1,669.15

Therefore, 7% of the total cost ($23,845) is $1,669.15.

To solve the proportion, cross-multiply:

7 * $23,845 = 100 * x

166,915 = 100 * x

To solve for x, divide both sides by 100:

x = 166,915 / 100

x = $1,669.15

Therefore, 7% of the total cost $23,845 is $1,669.15.
