Each kilogram of shrimp costs $13.56.

This problem can be solved using ratios and proportion. It can be solved using an equation with one variable.

STEP 1: Sort the given.

To solve, first we must sort the given in the problem:

cost of 3 kg of shrimp = $40.68

STEP 2: Represent unknown as variable.

If we let x be the cost of one kilogram of shrimp, we can represent the given above using the equation below:

[tex]\boxed {3x = 40.68}[/tex]

STEP 3: Solve for the variable.

Then we solve for x to get the price per kilogram. To do this, we divide both sides of the equation by 3 to cancel the coefficient of x:

[tex]3x = 40.68\\\frac{3x}{3} = \frac{40.68}{3}\\\boxed {x = 13.56}[/tex]

Therefore, the price of one kilogram of shrimp is $13.56.

STEP 4: Check answer.

To check if the answer is correct, we substitute the value of x into the equation and see if we get the price of 3 kilograms of shrimp:

[tex]3x \stackrel{?}{=} \ \$40.68\\3 \times \ \$13.56 \stackrel{?}{=} \$40.68\\\$40.68 = \$40.68[/tex]

Therefore, our answer that one kilogram of shrimp costs $13.56 is correct.
